Roger Johnson was disappointed the referee allowed Liverpool's opener to stand against Wolves after insisting he was fouled in the build-up.[LNB] Johnson diverted the ball into his own net after 11 minutes at Anfield as he dived to try and block Charlie Adam's shot, which had been heading wide.[LNB]But he believes play should have already been stopped after a challenge with Carroll moments earlier had left him on the floor and scrambling to regain his bearings.[LNB]"I don't feel there was a push, it was an obvious push," the defender told Wolves' official website.[LNB]"I knew it when it happened and I've seen it on the video. The ref doesn't give it but there's no point arguing about it afterwards because it's done.[LNB]"It led to the goal so it's disappointing and the ref was in a good position. He said afterwards he didn't see it as a foul.[LNB]"There was a period after before the goal went in as the ball went back out and Charlie Adam beat one or two and got the shot in.[LNB]"Unfortunately it was going well wide but I put it back on target.[LNB]"I wasn't to know but I'm always going to try and get the block in and sometimes it goes for you and sometimes it doesn't."[LNB]Despite going down to a third successive defeat at Liverpool, Johnson was at least encouraged by an improved showing following the poor performance against Queens Park Rangers last time out. [LNB]"Last week we let ourselves down massively and said to each other at half-time on Saturday that we shouldn't just quit because we were 2-0 down," added Johnson.[LNB]"We wanted to show a good account of ourselves and I felt we did that.[LNB]"It's disappointing to come away with nothing but at least we had a go."
