Arsenal also have their eyes on Ake

The situation is the following: Chelsea, Arsenal, Man City and Tottenham. Those which are the most likely to sign him are the Stamford Bridge outfit because they have a buy back option on the player. 

The latest to join the race to sign him are Arsenal, according to 'Telegraph', who says that the board are working on how to get him. His market value is almost 25 million euros and he cost his current employers 23. Therefore, his asking price is expected to shoot up. 

It is not known how much Chelsea will have to pay if they want to bring him back. In any case, they will have to fork out a large amount of money for him because the player's contract runs until 2022. That means there is no way of getting him back soon for free. 

Why do they want him? Because he has been playing brilliantly for Bournemouth for three seasons, where he has become a main man in their defence. This season, he has already made 16 appearances - all of them as a starter - and he has even scored one goal and set up another.
