There was a moment yesterday where he received a lateral pass under pressure, let the ball run across him and turned smartly away from trouble. But the rolling ball was quicker than he was, he looked like he was treading treacle just to catch up to it and ended up stretching to toe the ball, bobbling and off target somewhere in the general vicinity of a teammate.
He's not been 'overused', or 'asked to do too much' in the absence of more physical support; he's just not physically able at this level, in this league. Play Thiago at six, move on.
