Fed up of people claiming it's all to do with Pulis. All he had to do was play him regularly, it's disrespectful to Adama himself who's probably worked very hard to get to the level he's at now. It shows how crap Pulis was by the fact that he still mentions how he developed Adama every time he gets a microphone infront of him, literally no other successes to mention.
I think the reason he's not yet broken into the national team is the same unfortunate reason he'll probably never be a regular for Spain, their racist history is still very much prominent, I think Marcos Senna is the only black player I've seen play regularly for Spain. Iñaki Williams is one of the best forwards in the country but doesn't get a look in because of his skin colour. I know some won't believe this is the reason but racism is still a big thing in many European countries particularly Spain and Italy.
