Coombs Gyokeres would be better than Trossard on the wings. No debate.
But why even have that debate? Just put Gyokeres up front all season, rotate with Havertz in the league cup (who is still a 15 goal a season striker) and get top quality wide player. If there's still a chunk of change left (and time) we can go in for Sesko and start stock piling talent.
Collection A: Saka, Gyokeres, Martinelli, Trossard, Havertz, Sesko
Collection B: Saka, Gyokeres, Rodrygo*, Martinelli, Havertz, Trossard
I make Collection B > Collection A
*replace for whoever your ideal available winger is.
