Barcelona defender Marcos Alonso is set to undergo surgery in a bid to resolve the back problems which have limited his appearances this season.

Alonso has started just four games in the current campaign and appeared three times as a substitute.

The 33-year-old has not featured since playing the first hour of a Champions League defeat to Shakhtar Donetsk on November 7.

Barcelona did not give an exact date for the operation but said in a short story on their official website that an update would be provided immediately after the surgery.

Alonso joined Barca for £23million from Chelsea in September 2022 following a hugely successful six-year spell in London, during which time he helped the Blues win the Champions League, Premier League and FA Cup.
