Lyon coach Claude Puel saluted his players after their 3-1 victory over Bordeaux on Tuesday but warned there was still work to do in the second leg of their Champions League quarterfinal.

Puel's side will take a two-goal advantage into the return leg at Bordeaux's Stade Chaban-Delmas on April 7 after a Lisandro Lopez brace and a goal from Michel Bastos put them in the box seat at the end of a pulsating game.

Lisandro gave Lyon an early lead that was cancelled out by Marouane Chamakh but Bastos restored the hosts' advantage in the first half and Lisandro sealed a famous win for the seven-time French champions with a 77th-minute penalty.

"It was a very good match, each team had periods where it dominated," said Puel.

"They made things difficult for us by pressing us well at the start of the first half but we managed to score despite being on the back foot.

"They equalized quickly and that opened up the match. We started the second half slowly. Bordeaux made us run and almost got an equalizer but we started going forward, made some chances, got 3-1 up and had three or four chances to make it 4-1."
