I'm not sure about McCarthy. He's a good player certainly but for me he is missing something to make him a great player. I think that missing ingredient is drive and determination. I don't see it in him. Watching him always reminds me of Roy Keane, style wise, but unlike Keane he won't go out and dominate the game though he has the tools to do so. I think for that reason he's no better than what we have, except maybe Paulinho.
Isnt that what Poch is good at, getting decent players to perform better and working harder as part of a disciplined system. He may be able to make him set it up.
Roger Morgan works for the daily mail and does get good info.
