What worries me is not that he is too small, rather that till now he hasn't showed the characteristics of a "playmaker attacking midfielder". If you remember Nedved during his first years (with Lippi), Zidane, Del Piero when he plays abit lower down the field, or Totti with Roma, such a player passes the ball more and have much more creative ideas and a vision of how the attack should be. More over these players ARE ALWAYS available for their team mates to receive a pass. Even when Del Piero plays as a supporting striker he always gets closer to whoever has the ball to receive pass.
