Given the recent comments about stats I expect that Whitts is still one of our most productive players, and defensively he seems to be the one to make the professional foul time after time.
No one is saying he is the same player that scored 10+goals a season but his role at this club has changed and he still has much to offer. It may be the case that it some games it will be more beneficial to have a younger, quicker alternative but the fact that Whitts doesn't contribute as much in those games is as much the manager's responsibility as his.
He has a decent chance of finishing in our top 5 appearances and top 5 goal scorers and people will still be saying "he doesn't offer enough any more".
