Spanish side Atletico Madrid are desperate for defensive reinforcements with Lucas Hernandez heading to Bayern Munich and former Chelsea left-back Luis Felipe also set to leave the club this summer.
Atletico Madrid are also losing Diego Godin to Inter Milan, and 34-year-old Juanfran is also leaving the Spanish side this summer.
According to Daily Mirror, Atletico Madrid are confident of signing Chelsea left-back Marcos Alonso.
The report claims Alonso wants out of Chelsea this summer with Emerson posing a serious threat at left-back. Emerson started the Europa League final win against Arsenal.
Daily Mirror claim Alonso is currently in Madrid and is waiting for Chelsea and Atletico Madrid to reach an agreement.
Despite his desire to leave Stamford Bridge, Chelsea will be reluctant to let Alonso leave this summer as the club will be unable to sign a replacement for the 28 year old due to the transfer ban imposed on the Blues by FIFA.
Chelsea are in a strong position to keep the defender after he signed a new deal last season until 2023.
