I dont think its possible to be successful (by that I mean challenge for a title) with this midfield. Even with the best defenders around you cannot give away the ball in the sorts of positions we have been and expect not to get punished. We were weak on set pieces against Everton but at least 2 of those came directly from fouls Lucas gave away in dangerous areas and the 3rd as a result of a ridiculous mishit pass from Henderson. You cannot invite that sort of pressure on your team and then just blame the defenders.
Lucas had a good game, but all of that was undone with those couple of errors. There was one moment we've seen too many times (and it's not something that's exaggerated), their player was going nowhere, facing away from our goal looking for a pass, and Lucas inexplicably tries to tackle him from behind instead of holding him up and waiting for support, he does it time and time again and he has done since he came here. It's something he should have knocked out of his game given his experience, but he continues to undo what good work he has done in a match by giving away needless opportunities in dangerous areas. Exactly the sort of reason why people get frustrated by him and want better, I don't care how much of a fan people are or how underrated people think he is, it's brainless moments like this which prevent him being an intelligent, top drawer defensive midfielder.
Any one of Lucas, Allen or Henderson could get away with it with some real quality alongside them, try to create a partnership there though and we're trying to get blood from a stone in terms of creating a quality midfield. We need to spend money.
