9. Valencia
Just look at the talent in the above picture.
Juan Mata, David Silva and David Villa all came good during their time with La Liga side Valencia and all earned themselves mega-money moves elsewhere.
Mata went to the Premier League in order to join Chelsea, Silva followed suit at joined Manchester City, whilst Villa ended up at FC Barcelona.
However, out of the trio, Silva is the only one still at the same club as Mata moved to Manchester United and Villa is now in the MLS.
Imagine if Valencia managed to keep all those stars together?
