He did give the ball away cheaply, before Villa's second been a prime example. I think I watch a different game.
He does it far less. Also when he does give it away it tends to be at least when he's trying to do the right thing.
Think with his form you can almost do a post mortem of what has happened. I think under Ole, Ole just relied on him to try and 'magic' something up and sent him out there with instructions to do some damage, 'be your best you' or whatever else. The net result was a player who would, admittedly crop up with goals and assists but be tear your hair out level frustrating the rest of the time as he\d spend the other 90% of the match doing generally braindead things.
Under Ten Hag it seems like he is keeping what makes him a dangerous player but adding in better awareness and ball retention. In addition he is actually winning aerial battles and headers, something I thought I would never see the day of.
I have no complaints with his form at the moment. I do think he's just about value for the money he's being paid now, was an idiot contract he got those few years ago under Ole.
