Going streaking

Whether you're lucky enough to still have your original wildcard stashed away in your back pocket or not, as we approach the second wildcard window, it's worthwhile putting together a transfer plan to best exploit the fixtures on offer. We have at least four transfers before then (GW16-19) followed by the important period right after we play the wildcard, so with that in mind, let's try and identify a few fixture streaks during which we might want to target specific players.

For simplicity I've only looked at streaks of four gameweeks here. In reality we might want to dig deeper into streaks where you like three out of four games, or four out of six, but this is the starting point, for better or worse. Double gameweeks will also likely cause chaos at some point too, but without knowing where or when they'll strike, their impact is ignored for now.

The below table shows the expected goal total over the four highlighted games above or (below) the team average. So a score of -1.5 suggests that the model believes Arsenal will score 1.5 less goals over those four games than their average GPG to date would suggest (that GPG is based on actual goals scored/conceded, not regressed or expected goals).


I'm going to keep the analysis brief as this data really speaks for itself, but there are a few comments to make on a couple of these streaks.

Arsenal and Liverpool have been firm favourites of fantasy managers to date, yet appear to be risky investments in the immediate future based on the above (more on Arsenal in the longer term below). Both face three away games in the next four, including trips to the likes of the Etihad, Stamford Bridge and White Hart Lane. Does this mean you should be targeting Suarez and Ramsey for sale? Probably not, as they still do very well in the weekly rankings, but the lesser players from those sides should be considered expendable, particularly on the defensive end of the pitch.

Sunderland look like they enjoy incredibly easy fixtures as they're forecast to well exceed their goals scored and conceded tallies to date. However, this is more a product of the model thinking they've been somewhat unfortunate to date rather than the fixtures being unbelievably favourable. Saying that, over the next eight gameweeks they do get a number of promising fixtures (NOR, @CAR, AVL, @FUL, SOU, STK) so players such as Giaccherini or Johnson could make useful 4th midfielder types in paired with the right complementary piece.

The model loves Arsenal after GW19, and well it might given their fixture list of @NEW, CAR, @AVL, FUL, @SOU and CRY. This is one situation when careful planning is required, as to potentially get a 1.5 goal bonus on top of the excellent form this team has already shown suggests we should really be trying to squeeze an extra Gunner in our team for this period (the start of that period nicely coincides with the opening of the transfer window so they should be a hot commodity for wildcarding teams).

Another team whose assets you will want to maximise coming out of the transfer window is Man City. They get CRY, @SWA, @NEW and CAR from GW19 - 22, a period of fixtures that suggests we should try and squeeze at least one more attacking player into our sides alongside the presumably ever present Aguero. It isn't always easy to identify such players in this changeable City side, so here's hoping we're seeing some vintage David Silva play by the time Santa delivers that appetising run of games.

West Brom are a massively underrated defensive side with ownership numbers of 3.0% or less across the whole back five. Granted, the results of late have taken a turn for the worse (no clean sheets in the last five games) but they still boast excellent +/- scores of -19% at home and away and have four teams on deck who are all struggling for goals right now (@CAR, HUL, @TOT, @WHU).

Gameweek 9 Preview



Given how early in the season we are, the model is still liable to throw up the odd outlier and so in these weekly posts I plan to address those, shall we say, unexpected results. In future weeks, the plan is to post the data as soon as possible after the final games' data is up and then you can raise questions/issues during the week, to be addressed on either the following Thursday or Friday. For this week, I'll just try and guess where the questions might lie:

Keiren Westwood
Sunderland have conceded at least two goals in six straight contests, yet the model thinks they'll do okay this week. What gives? Well, having conceded 7.3 shots inside the box at home, they're hardly a team without hope (that alone would be the 9th best total of the teams playing this week). Add to that the fact that Newcastle have averaged 30% less SiB against their opponents than average, while only averaging 6.0 SiB on their travels, and you get a game where we're expecting Sunderland to only concede a handful of good chances (5.3 SiB) which gives them their best shot at a clean sheet to date (36% based on historic averages for team surrendering those shot totals).

Seamus Coleman over Leighton Baines
In reality this ranking is too close to pick between and essentially the model is saying they are equal. Baines is actually worth a little more because we know he has a steadier source of shots from set pieces, but those from free kicks are of course built into the model already, yet Coleman still comes out on top. Coleman has accounted for 6% of Everton's SiB compared to just 2% for Baines, hitting the target more frequently (50% vs 25%) too. Baines has a very slight edge (15% vs 13%) in the created chance department but to date these players have been very close and the 2.1m premium looks tough to justify.

Mezut Ozil
As much as Ozil has impressed to date, his current forecast of close to eight points looks aggressive compared to his peers who top out at just six. The only real explanation for this is small sample size and some of his somewhat fortunate conversion rates which aren't fully regressed in the weekly forecasts. The main culprit is that 88% SoT% which inflates his shot expectation for the week, even when adjusted for his historic average. Saying that, the data suggests Arsenal to top 13 SiB and 20 total shots, which is almost unprecedented and with Ozil being a central part in everything good about the Gunners to date, it's tough to argue against him being the top pick this week, even if the margin is probably a bit smaller than the model currently suggests.

Tottenham
Where are all the Tottenham players? Paulinho (3.7) and Soldado (3.5) are their best options yet find themselves way down the rankings in 16th and 12th places respectively. With a home fixture against Hull, most probably expect them to murder their opponents this week, yet the data suggests otherwise. First, Spurs are only averaging 6.8 SiB at home with a +/- of just 8%, both of which put them in the same league as Sunderland and Norwich rather than Arsenal and Chelsea. Second, Hull have actually been relatively good as suppressing shots away from home and while the results haven't come, they can be forgiven for shipping goals at Chelsea, City, Newcastle and Everton. McGregor's ranking shows that the model doesn't think Hull can necessarily go to White Hart Lane and keep Spurs at bay, but a thumping is not the forecast result either which limits the upside of Soldado and company this week (though he and the other Spurs stars remain solid starters).
