Lamptey and Sanchez are both worth a lot in terms of potential. We should hold on to them until they mature.
Both Bissouma and Trossard have matured. Bissouma takes it here as he is better in his position than Trossard. Trossard needs to add goals to really kick on.
Trossard for me. Bissouma’s contract is an issue along with, er, other matters. Lamptey has the Chelsea sell-on clause, and goalkeepers are often under-valued despite their importance to a team. Trossard is versatile and has a pretty impressive showreel that will attract the club owners who are seduced by spectacular goals.
