Hope we can get someone to update the team rosters now that Jan transfer window's closed. I know I've asked and someone else too, and it's not a big problem at all of course (and I DID notice the addition of Cenk Tosun to the correct squad so thanks guys, I know you're watching;)).
As I said, Transfermarkt is the key;) Ighalo for Man U on debut anyone?
The reason why it is getting more and more challenging is the fact that players who started awesome at the early stages of the season up until today were the great players teams had but now the season is on its back heel and that means injuries, fatigue, strategical prepared defenses and many other stuff that normally wouldn't happen on lets say first 10 games of the season.
With that in mind, 0 out of 7 is still bad but also I wouldn't be shocked if we had zero 7/7 this whole season from now on and next year would have some on the first weeks, that is a better period to make these predictions and that is why there was so many 6/7 people around at the early stages of the season, because players were still playing with some sort of high condition that they don't have at this stage.
That's pretty much typical for form anyway. Even Aguero, who has been consistent on a season-level for so many years now, actually always has bouts of injuries or a string of games he hasn't scored. Salah had his wonder season, but actually also has a stretch of games where he won't score, that's true for 3 seasons. Practically every striker kind of has this kind of form but yeah, you want to generally keep an eye on opportunities created and chances taken and hope the maths adds up.
I haven't got a 0/7 yet I believe... but I agree, it's going to get harder, not easier.
