I think Traore would be brilliant linking up with Kulusevski down the right side, I do think we lack a bit of pace and power in the team. Bissouma or Phillips added to our centre midfield would give us a bit more power in midfield too. A midfield 4 of Perisic, Bissouma, Skipp, Traore would be superb I think, especially with the technical skills of Kane and Kulusevski ahead of them.
Instead of teams only having Son to worry about as a player running in behind, they'd have to contend with Perisic and Traore wide too. Though I must confess, I don't know much about Spence, maybe he could provide the same.
