So what are you talking about here, mobility with the ball or without it? Are you worried about players taking the ball off Barry or are you worried about how Barry can dominate opponents?
Do I worry about Barry against Milner, Henderson and Lucas?! Absolutely not. We have McCarthy and Barkley in there providing mobility. Lucas is a snail mate so no idea where you're getting this 'runs round like a rabid dog' from.
Herrara barely plays. Schneiderlin is mobile but plays Barry's position for the opposition, how many times is that going to be a realistic duel?
Matic....pace?! Get in the bin mate. He reads the game brilliantly which actually makes up for the fact he is moves like he's in quicksand. His whole game is based on getting it and giving it. When does he ever drive with the ball into the masses?! He does the exact same job as Barry.
You're thinking of the Toure of 2 seasons ago mate. Without the ball he's about as immobile as it comes. Completely uninterested. Fernando and Fernandinho are sat on top of their two centre backs offering protection 9 times out of 10.
Going back to my original point, what are you worried about? As far as I can see there is only Tottenham in this league that press high with agile, athletic centre midfielders that would and have put Barry under pressure. I don't see another team who is going to risk coming on to us when the two centre halves split and Barry goes and collects. No team has done that to us this season APART from Spurs.
So I ask again, a)what are you worried about b) name the teams that you think will press GB high up the pitch where he does most of his work starting attacks?
