Barcelona stumbled to a goalless draw with Galatasaray in their Europa League last-16 first leg at the Camp Nou on Thursday.
Xavi Hernandez’s Barca, playing in Europe’s second-tier competition for the first time since 2004, dominated for long periods.
But it was their Turkish visitors who almost grabbed a lead ahead of the return game in Istanbul next week, with Bafetimbi Gomis only denied a winner by a VAR review for offside.
Memphis Depay, making his first start since December, forced Galatasaray goalkeeper Inaki Pena into two good first-half saves.
Xavi’s side are still unbeaten in 90 minutes since defeat by Bayern Munich in their final Champions League group game last year.
But the Catalan giants will likely have to find a victory next Thursday to extend their bid to win this competition for the first time.
