Arsenal Transfers: 10 Possible Signings To Win The League

6. Diego Costa

One of the most watchable players all season, Diego Costa would also be a big statement of intent, should Wenger sign him. With 19 goals in 17 appearances this season, Costa's not only one of the most prolific players in Europe, he's quick, cool in front of goal, and the prospect of seeing him link up with the likes of Ozil and Cazorla is mouth-watering. The buy-out clause in his Atletico Madrid contract reportedly sits at £33 million though: would Wenger take a risk on a player that hasn't played in England? It could take him a couple of months to settle in, after all. As long as he doesn't follow in the footsteps of Jose Antonio Reyes or Julio Baptista, the Gunners should be fine.
