Kightly has been a flop in the Premiership, I don't see any reason to believe he would be better than Routledge. Eagles' has been great every time I have seen him play, though.
People have been talking about Milijas. He's great on the ball, but he seems to have Nolanesque presence on the pitch. I'm afraid you'd need a midfield of 3 to accomodate him.
Kightly has been injured most of the season to be fair to him. Matt Jarvis has looked sporadically good for Wolves in his place.
Milijas although good is 27 and as Fat Ashley is the new Wenger is a no no. Agree with the 3 man midfield comment n all.
EDIT: You know of any young(ish) guns in the Spanish game who would improve us? (realistic obviously)
