Do you want CL or do you want to develop players?But what does that do for the development of Holtby, Eriksen, Sig, Carroll.
You need to earn your spot.
If there is any possibility of us having a better player in a given position, I would much rather they played important competitive games than lesser players who are "developing".
Another thing is (I'm not really sure I buy into it, but many people seem to believe there is something to it) if you could choose your mentor as a football player, would you like to be mentored by Sigurdsson or Kaka?
I would like to add that at no point did I state that there is a 100% certainty Kaka will be better than any of our current players, but I think it's highly likely.
