19. Santi Cazorla (Arsenal)
One of the bargains of the season has to be Arsenal’s Santi Cazorla, who joined the Gunners for between £12 and £15million, but whose influence on the team this season has seen his market value rise to between £31.7 and £36.8million this summer. The talented Spaniard is another player at the height of his game, and is certainly the heartbeat of this current Arsenal side, scoring 12 goals and providing 12 assists of the highest quality to help Arsene Wenger’s side to fourth place.
