Nobody has mastered the art of developing players and selling them at profit and still managing to compete at the highest level more than Arsene Wenger. The Arsenal boss had his hands tied in the last decade after the move to the new stadium but has now received funds to spend big and build a team with world class players again.
Qualifying for the Champions League every season is no mean feat and Wenger managed to do so on a shoestring budget compared to the Premier League elite. And he did so with players he trusted, nurtured and developed at the club even if the loyalty was not always repaid.
It comes as no surprise that their recent acquisitions are still their most valuable. Alexis Sanchez (£46.8m) and Mesut Ozil (£42.5m) would be valued much more if they sign the contract extension. Both their deals run out in 2018.
Other players who have seen a remarkable rise include Aaron Ramsey who is valued at £29.8m after he was signed for just £5m and Hector Bellerin (valued at £17m after signing him for less than half a million). Laurent Koscielny is valued at £18.7m.
