I don't think it's that bad, to be honest. It's based on player rating for individual games and we've not played well in most of ours.
Hojbjerg and Kane have been consistently good, but has anyone else? Son did well in a number of our early games, but he's been poor in the last few.
We've won games when we haven't played well and failed to win games when we have, which will give odd scores.
Vestergaard got murdered in few games, so I've no idea why he's up there, but Southampton and Leicester have generally played well.
Mendy's ratings are probably boosted a bit by the contrast to Kepa, who was objectively awful.
Neutrals are also more likely to be kind with their ratings to underdogs and we're rarely that nowadays.
Rodrigo's one goal and no assists being above Kane's seven goals and eight assists is quite funny, though!
