Dave Rennie says his team have "certainly got to get better"

The loss means Warriors slip off top spot in Conference A as Tommaso Allan's second-half penalty clinched Benetton's victory at the Stadio Monigo.

The Warriors had led 14-12 at the break but fell short against their Italian opponents, who recorded a fourth straight win.

Dean Budd grabbed two first-half tries for the hosts and Braam Steyn added another in the second period, while Glasgow's tries came from Sam Johnson and George Horne.

Replacement stand-off Brandon Thomson had a chance to earn his side a draw in the final minute, but fired wide from in front of the posts.

Frustrated Glasgow head coach Dave Rennie told BBC Scotland: "It shouldn't be coming down to a kick like that. We had a number of opportunities in both halves and didn't turn it into points.

"We made a lot of handling errors, as we have in the last two weeks. It's a combination of that and some of our decision making."

Warriors squandered opportunities to score, as Adam Hastings passed forward to Nikola Matawalu, who would have had an easy run-in, and prop Alex Allan was somehow held up over the try line.

And despite having significantly less possession and territory, Benetton disrupted Glasgow's attack.

"We lost the collisions, we lost the battle of body heights," Rennie said. "There were various times where we had 15 phases plus, but eventually it broke down. You've got to give credit to Benetton."

Glasgow next face Cardiff Blues in the penultimate round of European Champions Cup pool matches, and still have the chance to qualify for the knockout phase.

They beat the Welsh side 29-12 away from home earlier in the competition but Rennie says his team have "certainly got to get better" to produce the same result at Scotstoun next Sunday.

"Cardiff are a very good side and are playing some good footy," he added. "We need to be able to hang on to the ball for long periods and we need to defend a lot better."
