According to Spanish outlet AS, Diego Simeone is a big admirer of the Blues full-back and wants him to replace Filipe Luis, who is set to leave Los Colchoneros at the end of the season.
Ex-Chelsea left-back Luis is set to bid farewell to Atletico after spending nearly ten years with the club in two spells in the Spanish capital.
Alonso, who replaced Luis at Chelsea, has had a mixed season at Stamford Bridge.
He has been in and out of the line-up following a poor patch of form, with Emerson replacing him in key matches in recent months.
The midfielder was withdrawn during Chelsea’s friendly against New England Revolution on Wednesday evening with an ankle problem.

He left the stadium on crutches with his left foot in a protective boot amid fears he has suffered ligament damage – and early reports suggest the 23-year-old is facing a lengthy spell on the sidelines.
However, in some good news for Blues fans, reports suggest Callum Hudson-Odoi is close to penning a new five-year deal at Stamford Bridge.
The youngster will reportedly sign the long-term deal to commit his future to the Blues and put an end to rumours linking him with a move away in the summer.
