Erik Lamela deserves an upgrade. He has played 15 games and scored 10 goals as a right wing being A.S Romas topscorer which is quite impressive. He is already a very good technical player in FM but his finishing and longshots should be better.
I think Chamberlain needs to be faster. He starts the game with 14 acceleration and 16 sprint speed. He isnt as fast as Walcott but still a very fast player. Should be like 16/17 acceleration and 17/18 sprintspeed.
