This is a useful chart - however for PL purposes Perrone & Gvardiol go into B List (they were born on or after 1 January 2002). although can not be in the B-List for CL as they have not been in England for long enough. Therefore we still have 2 places free places available (for PL) even if Cancelo and Laporte do not move
Palmer, Lewis & McAtee, Harwood-Bellis, Doyle, should all be in the B-List. Which means we could sign any Club Trained Player to fill those slots ( e.g Trippier, Diaz, Denayer, Gunn, Angelino [again!] Porro, Tosin - not that I'm suggesting any would fit the bill)
