Dave Rennie says the amount of turnovers Glasgow gave away was unacceptable

Warriors were outscored three tries to one and put in an error-strewn performance against the reigning champions.

Finn Russell and Leigh Halfpenny missed two kicks apiece in the first half before Rhys Patchell shrugged off some weak Glasgow tackling to open the scoring.

Halfpenny was back on target in the second half, with Gareth Davies' interception try stretching the lead.

Glasgow pulled one back through Henry Pyrgos, before Patchell added his second of the afternoon.

Despite the defeat Glasgow remain top of Conference A with a healthy advantage over second-placed Munster and look set to secure a home play-off.

Speaking at full time Dave Rennie said: "It was a disappointing performance, we need to be better.

"One thing we've done really well this season is be really accurate and clinical and that wasn't there today.

"There were too many handling errors, when we finally put Scarlets under a bit of pressure we let them off the hook. Overall it was a pretty flat performance.

"The amount of turnovers we gave away was unacceptable.

"We kicked the ball away too much and need to be a bit more patient, go through the phases and not try and pull a rabbit out of the hat."

He admitted that the fault doesn't lie solely with the players, stating that everyone will be pulling in the same direction next week to get a better performance against Connacht on Friday night.

"From a coaching point of view maybe we got it a bit wrong, tried to cram the guys' heads with too much this week which made us a bit sluggish so we'll make sure we get it right next week."

Should Glasgow beat Connacht at Scotstoun on Friday night they will tie up top spot in Conference A and secure a home semi-final.

Scarlets are a possible opponent should the Warriors get there, an opportunity to make amends in the mind of Rennie.

"We're looking forward to playing them again. We're not looking for excuses, a few international boys came back in we just weren't as sharp as we needed to be.

"We get three more cracks at it prior to play-offs and if we face Scarlets again this season we'll use today as motivation.

"A six day turn around suits us, the quicker we can get out there after that performance the better.

"We've got good depth within the squad so there are others who will be putting their hands up to play next week."
