The Blues claimed last season’s Premier League title and reached the knockout phase of the Champions League, they also lifted the Capital One Cup, but manager Jose Mourinho remains keen to add more quality to his ranks.
The 26-year-old recently lifted the Russian title with Zenit, and has since confessed that he’s ready to move on to bigger and better things.
The ex-Benfica man would add greater physicality to the Blues’ ranks, and could provide competition for Cesc Fabregas and Nemanja Matic, or potentially free up the former to move into a more attacking role.
In order to make a swoop possible, Chelsea are looking to offload Mikel, with interest from the Middle East and Turkey strong.
The 28-year-old has been a Stamford Bridge star since joining the club in a somewhat controversial deal from Lyn in 2006.
