Portugal Colonial - Barca held by Galatasaray, Rangers thump Red Star Belgrade

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.

Jordi Alba, Ousmane Dembele and Frenkie de Jong all went close in the second period for Barcelona, but the hosts could not find a breakthrough.

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.

Rangers took a big step towards reaching the quarter-finals for the first time since losing the 2008 UEFA Cup final to Zenit Saint Petersburg.

Giovanni van Bronckhorst's men backed up their stunning win over Borussia Dortmund in the play-off round with another dominant first-leg performance against Red Star at Ibrox.

James Tavernier's penalty and Alfredo Morelos' 28th career goal in the tournament put the home side in command.

Visiting midfielder Aleksandar Katai, who had earlier seen two goals disallowed, then had a penalty saved by Rangers goalkeeper Allan McGregor.

The Scottish champions took full advantage, with Leon Balogun adding a third six minutes after the break to put the Glasgow giants in total control heading into the second leg.

Atalanta will take a lead to Germany next week after Luis Muriel scored twice in a 3-2 win over Bayer Leverkusen in Bergamo.

Leverkusen winger Moussa Diaby's 63rd-minute strike, his eighth goal in seven games, kept the tie on a knife-edge.

Elsewhere, Abel Ruiz scored in the first minute as Braga beat Monaco 2-0 in Portugal, while Munir El Haddadi gave Sevilla a 1-0 home win over West Ham in the early kick-off.

Leicester saw off French side Rennes 2-0 at the King Power Stadium as Kelechi Iheanacho's injury-time effort added to Marc Albrighton's opener on the half-hour mark.

Jose Mourinho's Roma claimed a 1-0 win at Vitesse Arnhem and Marseille conceded a late goal in a 2-1 success against FC Basel at the Stade Velodrome.
