Well it's hardly as clear cut as, Wenger rotates too much vs Wenger rotates not enough. You won't have heard me criticise him for rotating. Wenger rotates when he feels it's necessary fitnesswise and consequently more for some players than for others. Wilshere is a case in point. Played 49 times last season, more I think than other player. This is a kid in his first full season.
Yes, a settled team is better, but the days when you could win the league with 14 players in pretty much over. And I'm an advocate of not dicking about with a winning side.
To continue to play Wilshere in meaningless games at the end of last season seems strange to me. And given his stress fracture injuries I don't think you can really argue that he wasn't overplayed.
Tottenham apparently have Walker, King, Van Der Vaart and Adebunghole out injured atm.
