Pass into the box? Mate he played a 3 yard ball backwards. The fact that Davies was in the top corner of the box means nothing there. It wasn't a scoring opportunity. Davies did all the work and put the actual quality pass in after that.Sigurdsson has 11 completed passes into the box. Gomes has 11 completed passes into the box. Iwobi has 25.
Sigurdsson has completed 3 crosses in the box. Iwobi has 8.
Now would I say either is doing enough per 90 minutes? Maybe not. But this is why numbers matter, because you can get the perception that someone does something that they don't actually do.
Iwobi has been playing as a winger this season so I would obviously expect him to have more crosses and be sending more passes into the box. His job is to create and he's very poor at that.
Sigurdsson plays in the middle where you usually don't cross the ball, mainly because he isn't perpendicular to the box but instead has it in front of him.
Gomes plays as a 6 or an 8.
These comparisons you have picked are absolutely useless and make no point at all.
