You can get someone with Prem exposure but someone who is still young and can be coached into that role for either flank.
Gnonto and Olise are the ones. Prem experience based, Raphinha qualifies but he’s not a name that should be considered as he’s stagnated a fair bit. Other names that come to mind are Mitoma (no chance Brighton sell) and Zaha (free agent, but too old and I do not think we are aiming for someone as direct).
Outside the league there are lots of prospects. Barcola being one of the main names, another couple can be taken from La Liga. Yeremy Pino is one of them. Lastly, and the most suitable name in my opinion is Samuel Chukwueze, right profile, can play on either flank, very good on the ball, great work rate, most likely has a release clause that Txiki can sort out, has European experience with Villarreal and still young, hope we look at him.
