Exactly. I really dont know sometimes why these young players get impatient and move prematurely, before establishing themselves. Chelsea, Man City & Man U in particular are volatile clubs where you can be dropped just if the manager doesn't like the idea of playing you. I feel like Lukaku timed it right - 3 seasons of consistency with us, and then the move at the right time - though I don't think he'll make it to Aguero, Higuain, Shearer's levels - let alone Ronaldo, Messi, Neymar. But still it was timed ok and was good for everyone. Barkley, Stones, Rodwell, Jeffers...
