I won't pretend to have watched him a lot, but having watched him in the Europa final, I did have some concerns so maybe someone who has seen him more can break down.
His number of assists are impressive, however the commentator said he was first in the number of crosses into the box during the Europa campaign, but watching his crosses they were often hit blindly and almost constantly. So are his numbers actually good, or is it just a reflection of the shear number of balls he pumps into the box?
He also seemed to lack composure overall, he seemed to be their main attacking threat but was pretty rash with his decisions and shooting.
It was a final, so in fairness to him I imagine the occasion played a part but overall I didn't come away thinking he was a sign at all costs type of player.
If the intention was to rotate between him, and Sessengnon then I think it would be a fantastic signing for a comparatively cheap fee.
