Elmohamady, Jedinak and Bjarnason of the current crop.Off the top of my head, any of the likes of Milner, Young, Cahill, Walker, D**ph, Bertrand, El Ahmadi (as you spotted), Benteke and Gana Gueye may well be involved if we just include players "with Villa connections".
I've further discovered that Mustapha Hadji is Morocco's assistant manager... so let's broaden it to ex-Villa players managing/coaching at the World Cup too.
