Michu for Swansea
Pukki for Norwich
Guiza at Mallorca
Dempsey at Fullham (I think?)
Van Wolfswinkel had a period with a fair amount of goals for Sporting.
For strikers/attacking players this seems easier.
Nuri Sahin, did good enough at BvB and got himself a transfer to Real. Barely played and haven’t heard of him since.
