Mirth Even for Sweden it’s Isak that gets the freedom to drift wide.
Sweden usually play a 4-2-3-1 variant that looks more like a 4-4-2 or perhaps a 4-2-2-2 on the actual pitch to me, but it's pretty fluid. Both Isak and Gyökeres drift a lot but neither is really a winger.
Gyökeres does work the channels a lot for both Sporting and Sweden though, and due to his two-footedness he works well on either flank. I think he would help the wingers overload the fullback.
You could probably play Sesko and Gyökeres together, but Sesko would most likely drop down in the hole which is how Leipzig has sometimes used him. I don't think it would be bad news for Martinelli but rather Ødegaard if it were to happen. I understand he had a pretty bad season?
