Warrington coach Tony Smith accepted his side had won in ugly fashion after overcoming Catalan Dragons in bruising a encounter at the Halliwell Jones Stadium.
The unbeaten Wolves ended the Dragons' 100 per cent start to the Super League season by grinding out a 24-16 victory in an ill-disciplined contest.
Smith said: "It was horribly messy and scrappy. It spoilt what could have been a good game. There was a lack of control and we got dragged into it.
"It was a bit like a dripping tap and sometimes you have got to turn it off.
"There were a couple of nasty incidents in that game. There is a difference between nasty stuff and tackles that go wrong."
Both sides ended the game with 12 men after Brent Webb and Westwood were sin-binned with eight minutes remaining and the problems almost continued on the touchlines. Webb had also been yellow carded in the first half for interference.
Smith said: "I am good mates with Webby. I have coached him and have a lot of time for him as a player but he lost his rag there.
"I didn't want Bennie to get dragged back into it. It's a shame we are talking about that. It was good tough footy for a lot of parts.
"I thought we did a bit but still conceded too many points. We are still working our way into the competition. We are going to get stronger and better as we go on."
Smith confirmed that playmaker Lee Briers had missed the game with a neck and shoulder problem while prop Adrian Morley, injured early on, had torn a biceps muscle.
Dragons coach Laurent Frayssinous, whose side also had Julian Bosquet sent off against Salford last week, accepted discipline must improve.
He said: "We need to be more disciplined with the ball, in defence and with the ref as well. We had a lack of discipline and concentration."
