GLASGOW WARRIORS coach Dave Rennie wondered if his side’s preparation was up to scratch and why the 2015 champions lacked energy in their nine-try defeat to Leinster on Friday evening.

The Scottish side conceded their first try after four minutes and they continued to be scored in regular intervals, with Leinster’s dominance only periodically interrupted by tries from Tommy Seymour, Kyle Steyn and Alex Allan.

Warriors’ poor night was epitomised by Dave Kearney’s third try in the final play, which arrived when a Warriors player tried an impossible under-arm off-load behind his own posts, and Rennie didn’t have too many answers as to why his side were so out-played.

“Obviously that’s an incredibly disappointing performance from us. We were miles off it. Too many errors, too many missed tackles,” said Rennie, whose side face Ospreys next time out.

“Leinster are such a good side. They will get good momentum on the ball which generates really quick pill and constantly attacking seams and asking questions. They can go underneath you and they can hurt you out wide once they have generated some numbers around the ball.

“That’s really clinical so that’s a really good lesson for us. I know we lacked energy tonight for some reason in that battle to get bodies on bodies in our defensive line. They were good enough to hurt us.”

Unlike many of their Conference A rivals Warriors do not have any games remaining against the Italian sides, so there remains a good chance that all their eight games will be played in full.

But this defeat in Dublin could be significant. Glasgow still have to play conference rivals Ospreys and Ulster twice, while their final-round derby against Edinburgh could have a lot on the line.

With wins in their three PRO14 games of 2020, Warriors have recovered from a poor start to the season, but Rennie, pictured, questioned if something was askew in their preparation for the trip to the RDS.

“We conceded a lot of points because we just didn’t defend well enough. We made errors which were difficult to defend from as well. They are too good a side to keep giving possession away or give quick ball to.

“We have talked about how we prepared and so on, because preparations seemed pretty good as they have been in the last couple of months. But we were miles off it, we were well out-played and the score reflected that.

“Kyle Steyn’s try was really well finished, but that was one of too few bright moments tonight.

“It doesn’t change too much for us in terms of the general picture, and it’s not terminal. We know that we need to be at a higher level in these big games, though.”
