Just too many slow defensive players, combined with a high line and high press means just so easy for teams once they break past our initial press. And teams will break past the initial press, no matter how good it is.
Hate to single people out after a performance like that, but Mendy offers nothing. If you are going to be a liability defensively you have to be shit hot going forwards, but he offers nothing, just like ZInchenko.
We fall apart defensively when we get worried, we need a leader in that back line, Dias can't arrive soon enough on that front.
