Barcelona midfielder Sergi Roberto is reportedly a fitness doubt for the Catalan outfit's La Liga clash away to Atletico Madrid this weekend.

Luis Enrique's side are currently without first-choice right-back Dani Alves, who suffered a groin injury during Barcelona's 1-0 win over Athletic Bilbao on August 23.

Roberto replaced Alves in that position at San Mames, before starting the next league game against Malaga on the right side of the back four.

The 23-year-old was expected to start the match against Atletico this weekend, but according to Inside Spanish football, the midfielder-turned-defender is struggling with an unspecified injury.

Should Roberto fail to recover, Adriano, who is expected to pen a new deal at Camp Nou in the coming weeks, is the favourite to feature.
