Agreed - but the problem is one world class player a year could still take time to make a competitive team. Fabs was always going back to Barca no matter what which has left as with RVP being the only world class player we've had since the Invincibles. With all the improvements this year I still only class Ozil as our one true world class player, if its going to take another 5 to make us compete will he be around for 5 years. Unfortunatley immediate success is going to need quicker investment than that. No team has world class players in every position, even the great Barcelona teams of late regularly played Puyol, Pique, Mascarano, Busquets who whilst are very good team players, they are not world class.
If we're happy that Ches is starting to become top keeper, I think we need better full-backs & another centre back to partner Kos, we need world class DM & a world class striker. If we could find & buy these sooner rather than later, we can compete with anyone. The other issue is Wenger. I can't argue that whatever we do at Colney gets us playing nice football etc but he's tactically weak & is useless from the bench. We could do with someone on the bench who knows how to change things, to react in match situations. Wenger is clueless, his stubborness means he takes it personally if he has to change things becusae it would suggest he wsn't right from the start.
