It's a tough call I think; both knit the team together, linking things up, but most of all organising and doing a lot of work that's often unnoticed, especially Howson who was my MOTM today - he was outstanding and was the heartbeat of the team. I'm sure CW loves him, but wished he was 2 or 3 years younger too.
Grant enjoyed being part of a great promotion side, but before that his form wasn't at the same level. For two seasons though he was exceptional for us and a key player.
Howson has chopped and changed roles, which makes it more difficult to judge, but he's a more complete footballer though, more mobile and quicker.
Both deserve to be remembered as great players for us.
