Never going to be a long term solution but I've seen nothing in the friendlies and his appearances for loan clubs to make me think he's a calamity or likely to cause us unnecessary worry, if he does indeed play (as he should).
Looks a solid shot stopper, confident in the air and surprisingly good at coming off his line to claim stray passes. To be honest, he'll probably be better able to deal with the rough-and-tumble of the Premier League - which De Gea and countless other foreign goalies have struggled with - than Romero would anyway, considering his experience in the lower leagues. I suppose we just have to remember that he is a young lad, and as solid as he has looked, he is no De Gea and we can't expect the game-winning heroics we've become accustomed to from our goalie!
