Leigh Griffiths scored twice as Celtic defeated FC Malmo 3-2 in their UEFA Champions League playoff first leg at Celtic Park on Wednesday.
The Scottish champions raced out of the gates, scoring in the third and 10th minutes through Griffiths and Nir Biton respectively, with Griffiths' opener finishing off a fine, sweeping move by the hosts.
Jo Inge Berget, who spent last season on loan at Celtic from Cardiff, then netted in the 52nd minute to cut the Hoops' advantage, before Griffiths bagged his brace with with a looping header into the top corner of Johan Wiland's net 10 minutes later.
Berget then struck with virtually the last kick of the game to give Celtic a tough test in next week's away leg.
Sofiane Feghouli struck late on to help Valencia to a 3-1 defeat of Monaco at Mestalla.
Feghouli has been in talks about a move to Fenerbahce recently, but he was the hero, initially for setting up Rodrigo for Valencia's first in the fourth minute.
Monaco hit back just after the break through Mario Pasalic, but Dani Parejo scored his first Champions League goal to give Valencia the lead again before Feghouli made it 3-1 in the 86th minute.
Dinamo Zagreb had to come from behind to claim a 2-1 victory at the home of Albanian underdogs Skenderbeu Korce.
Skenderbeu, who are looking to become the first Albanian side to reach the Champions League group stages, took the lead through captain Blendi Shkembi, who curled in a stunning free-kick from the edge of the box.
But the visitors equalised through El Arabi Hilal Soudani and then sealed victory thanks to a second-half stoppage-time winner from Josip Pivaric.
Eran Zahavi scored in the sixth minute added on to give Maccabi Tel Aviv a 2-2 draw at Basel.
Zahavi put Maccabi ahead in the first half, but Matias Delgado was on hand to level from the spot.
The Swiss looked to have claimed victory when Breel Embolo made it 2-1 in the 88th minute, but deep into injury time skipper Zahavi headed home to give his team a second valuable away goal.
Shakhtar Donetsk put themselves on track for a sixth successive Champions League group stage appearance thanks to a 1-0 win at Rapid Vienna in Wednesday's other fixture.
Brazilian midfielder Marlos scored the only goal of the game in the 44th minute.
