That’s a fair point about the energy required for our pressing game - and it may be that diminishes a little as he gets older.
But let’s be honest - we have so much of the ball, his upside in what he brings to our play for the 70/75% of most games where we’re on the ball way outweighs any advancing limitations to his pressing.
Fair and I do like Mahrez - he has the best first touch of any City player I've seen. Happy to be proven wrong and I hope he does well.
