That's the thing. I've seen people on here dismiss Messi, saying he is over the hill, where would he fit in, etc?
You always find room for top players - admittedly, he is in a class of one.
All the same, we had Aguero, Dzeko, Tevez and Mario, and Mancini still felt it was right to push forward again with Van Persie.
We rightly become loyal to the players who are with us here and now, but Grealish really does improve our options, and you can never turn your nose up at that.
I do think someone like Sterling needs more than just Foden breathing down his neck, simply because Phil can play anywhere!
