WORCESTER Warriors' head coach Jonathan Thomas admits his side were the products of their own downfall in the 41-10 defeat to Exeter Chiefs at Sandy park on Saturday afternoon.

Despite leading at half-time by 10 points to 8, the Chiefs ran in five second-half tries to romp home to a convincing win.

Thomas pointed to physicality playing a major role in the game, especially in the second forty minutes but it is something that is a focus for this side.

"The challenge for us is physically, we're playing against physically the best team in Europe," he said.

"We are bringing in a new head of performance for that reason because physically we need to be better .

"There are a lot of things you can talk about in this game but the reality is they are big powerful men and some times you have to match power with power and size with size and that's part of the growth we have to go through around the club.

"So there's a huge amount to work on from that side of our game."

Playing with the wind on their backs in the first-half, Warriors managed to use it to their advantage and raced into a 10-0 lead inside 20 minutes.

Chiefs capitalised on a few errors from the visitors to reduce the deficit to just two at half-time and Thomas said that margin was not big enough given the conditions.

"First-half we played the conditions well," he added.

"We were disappointed to concede the eight points we did, the breakaway try when we kicked the ball away and then the three points from the scrum after Fin Smith kicked it dead.

"Obviously with the strong wind we needed to score more points.

"Our margin of the lead needed to be bigger than it was at half-time. Tactically we played well, there was a good work rate and I thought our set-piece was on top.

"But second half it reversed and we struggled. The big thing in the second half that killed us was our discipline; 13 or 14 penalties is too many, you cant give Exeter that many otherwise you cant get out your 22.

"In the contact we were also to high and when fatigue creeps in technically we were a bit poor. All the basics of the game that we did well in the first half we didn't do well in the second and then the damn burst with 20 minutes to go. The relentless nature of how they play, it took its toll."
