I think Fatawu is a good shout at RW, still young and developing. Brooks and Scienza I’m not sure, always think of Jack Clarke who is great at this level but not above it.
I think if it were me I’d prioritise a beast of a CF like that Denkey lad, similar in defence, maybe from one of the relegated clubs or a European, and someone who can take outstanding set pieces and I’d build us around that. Fairly direct, a threat at corners and free kicks, two or three long throw specialists in the squad (which we’ve got already tbf).
On set pieces I like the Moroccan LB at Utrecht who has 10 assists this season and Leeds and West Ham have been linked with. Available on a free too.
Then an elite shot stopper, hopefully Rushworth but got a feeling Brighton will want to keep him.
Just missing a CM, Hackney would be ideal if Boro don’t go up, otherwise look at Europe again maybe.
