Obertan surely is a player to watch but needs a bit of time because he's just came back out of injury.
Tosic should be given his chance to play in the first team now, Nani is not performing the way he should be so why not give Tosic a chance ? With Tosic we've got our new Ryan Giggs. This boy should break trough this season. Kiko of course is a great talent but should be given some time to develop and he will turn into a great player. Darren Gibson is ready for first team football, the midfield will be so strong with him playing next to Darren Fletcher or Owen Hagreaves. Cleverly will be a great central midfielder as well. Last but not least Danny Welbeck! Great player with bags of scoring potential, sure he will get his chances this season.
Welbeck, Gibson, Tosic, (Obertan) = ready for the Premier League
De Laet, King, Eikrem, Cleverley = Carling cup + subs
Manchester united have got the most young talents in the world.
