I’d also have to ask, who is defining ‘proven’ in this case?
This kid Soumare looked pretty good in Portugal’s top flight, a league at least comparable to the championship, if not better. His underlying stats look very promising, he’s young, and, most of all, he won’t cost an arm and a leg. Have we just never heard of this bloke and therefore dismiss him?
The footballing world doesn’t revolve around Britain, just because we haven’t heard of a particular player doesn’t mean he’s an unknown quantity or somehow worse than English players of a similar age. He could well contribute to our squad. My point is that people are way too quick to dismiss this lad just because they haven’t heard of him and write them off as unproven. As with any signing, it may not work out, but that shouldn’t stop us from potentially finding a midfield lynchpin.
As others have said, there’s no problem with there being a balance between signing championship/league one players and foreign players. I liked the signing of Tyler Bindon, and if this signing goes through, I’ll like it too.
