On the young players, I think most will and should be sold.
I don't know what will happen but 3 years down the line, of this crop maybe only 2 will start and 2 will be good bench assets. If I had to put a stake in the ground I think it's Saka, Martinelli, Nelson + 1.
Nelson will be the last to come good but he could be a Mueller type that Capi learns to love.
