Yes, but they are more natural fits on paper for Angeball.Doesn’t the ‘ far from a great one’ description refer to Johnson, Solomon and Gil as well?
Kulu lacks the natural agility and quick first step required of a touchline winger for Ange - the three you mentioned all have that going for them, regardless of other flaws, plus Bryan weighs a pass very well which makes him an interior option as well.
Kulu needs 40-50 yards of space to build up momentum to be an effective winger, he's mostly ineffective from a standing start.
