Chelsea could reportedly lose another senior member of their first-team in this summer’s transfer window as Marcos Alonso is linked with Atletico Madrid.

The Spanish left-back is said to be keen on a new challenge after becoming less of a regular for Chelsea this season, and the two clubs have already held discussions over a deal, according to Don Balon.

However, it’s fair to say the 28-year-old looks rather less at home in this current Chelsea set-up under Maurizio Sarri.

Playing as a more traditional left-back, Alonso has struggled to replicate his initial strong performances and Emerson Palmieri has seen increasing playing time as the season’s gone on, including playing 90 minutes in the Europa League final win over Arsenal.
