#2 Oriol Romeu
Former Barcelona and Chelsea central midfielder Oriol Romeu was widely expected to replace Frank Lampard at the latter of the two clubs but, bad timing and the pressure of having to settle in quickly, stifled his chance to reach those heights.
Now, under Claude Puel at Southampton, Romeu is flourishing. With 37 appearances in all competitions this season, he's amongst the first names on the teamsheet, given how important he is to the way the Saints play the game.
Only 25 and yet to represent the Spanish national team, Romeu is one of the most underrated Spanish midfielders. Should he continue his fine performances at Saint Mary's, he's sure to get in to the national team. It's only a matter of time.
