Finn Russell kicked two penalties but was sin-binned late in the first half

The result sees the Frenchmen go three points ahead at the top of Pool 4 with next week's match at Scotstoun vital to Glasgow hopes.

Toulouse were the more clinical of the two sides, with the Warriors paying for a lack of composure and discipline.

The opening period saw the Warriors press the French side's defence but they were unable to find a way through.

It was the hosts that hit the first points, with Jean-Marc Doussain knocking over a simple penalty before Finn Russell replied with his own three-pointer.

Chances were few and far between for the home side, but they came closest to scoring the first try just after the half hour mark. Maxime Medard made a superb break, feeding Gael Fickou, who played a reverse pass to Imanol Harinordoquy. His composure deserted him though, with the ball slipping out of his hands with the try line at his mercy.

They were ahead not long after though, with Russell sent to the bin for a dangerous tackle which allowed Doussain to put his side ahead. The fly half hit another just before the break which gave the hosts a somewhat undeserved 9-3 lead.

Seconds after the break Doussain played in a low kick into the left hand corner, which bounced up perfectly for Maxime Medard, with the conversion meaning the Warriors were 13 points adrift.

Russell kicked another penalty to cut the gap but Leone Nakarawa's sin binning summed up a frustrating night for Glasgow, and with 15 minutes to go they trailed by 13 points.

Glasgow had a bonus point to play for, and Nikola Matawalu's try put them within a conversion of getting one. He ran into the corner when he could have gone nearer the posts, which gave Duncan Weir a kick which proved too difficult, and the Scots went home empty handed.
