The German tactician had tried the 23-year-old left-back in the role back in pre-season when Inigo Martinez was dealing with discomfort before leaving the club for Al Nassr. Martin, to his credit, has taken to the role well and done enough to impress the Blaugrana coaching staff. Martin to start at centre-back again? So much so that SPORT reports that Flick is considering repeating the tactic once again tomorrow when Barcelona host Atletico Madrid at the Spotify Camp Nou.
