Well yes. We're basically in a position where we won't be able to take him at all due to the setback of relegation damaging our squad so badly and immediate fixes being the main priority.
I do think we can strike a balance. Colo, Jonas, Cabaye, Ben Arfa and hopefully Gervinho are all established players which aren't likely to improve in the future. Therefore we do have spaces for some youngsters to develop, e.g. Wickham, Vukcic or Abeid.
On the other hand, I don't think we can get Wickham 2 years later because he would join those mega clubs should he develop as expected. Just like Bale, he wouldn't be playing for Spurs now if they didn't get him when he is 17.
