The blame lies solely with Alzate for that. If you can’t control and pass a ball with 6 yards of space (even if you have to go back to Ryan who then goes long) then you shouldn’t be playing CM for a PL side.
What if you can't control and pass the ball with 6 yards of space once in 200 attempts? Or 300? You seem to be ignoring the 100s of times he got this right. He's a very fine young player, playing for a manager who doesn't jump on mistakes like an hysterical child.
