John Carew insists that he and his Aston Villa team-mates are pleased with the impact of new manager Gerard Houllier.[LNB] The Norwegian returned to the starting line-up for Villa's scoreless draw with league leaders Chelsea at the weekend.[LNB]Carew, who has worked with Houllier previously at Lyon, feels that Villa will continue to improve, as a result of the Frenchman's methods.[LNB]"Always with a new manager you have some new ideas and I think we've done quite well since he's come," said Carew.[LNB]"The team is very strong. It's important to develop with the games coming up.[LNB]"We work hard on new things and that's what we're all interested in. That's what we're here for - to make this club better and make the results better, to achieve goals and improve each season.[LNB]"If that means more work and harder work, which it probably does, then that's good."[LNB]Carew expressed his satisfaction with Villa's drawn result against Chelsea, despite being denied a golden opportunity by Petr Cech early on.[LNB]"We showed that we're really fit and we managed to keep them away and played out football quite good, especially in the first half," he added.[LNB]"So we have to be satisfied with a point against the champions of last year, take lots of positive things from the game and try to continue.[LNB]"We had chances but they had chances as well. In the first five minutes, I had a shot and as soon as I hit the ball I thought it was a goal but Cech managed to get his finger on it.[LNB]"They had a couple of chances too and they probably had the best one as well with Nicolas Anelka."
