"I'm a little bit frustrated," he said after the game at Ewood Park. "I felt we could win the game. In the first-half we didn't play very well but it was a difficult match. They were very direct and we were expecting that.
"After that we changed it with Ngog in attack and Nabil (El Zhar). We were more dangerous and had chances to win. They also had two counter attacks which could have seen us lose. But I think the team played much better in the second-half.
"It is a clean sheet and we played better football than the other day, so we are improving, but you have to win these types of games. We had chances, but you need to score from them if you want to win matches."
