Define “we”
Our starting XI as it has been? Without Henry, that’s no longer an option.
Ultimately we will adapt the team as needed to adhere to our own principles of play. If we don’t have a LB that slots into a 4 to gives us natural width and the outlet of raw pace on that side then just sticking anyone in there and playing the same way “because we play best in a 4-3-3” will not work.
We could move Hickey across and give our RB more attacking freedom, or we might adjust our formation slightly and see a different left-sided player give us that natural width higher up the pitch. That gives us a different threat, and perhaps more of a tangible goal threat, from that side. We have KLP that could play that role, for example.
