Paul Lambert felt Grant Holt was hard done by after Norwich's two goal hero was dismissed for a second yellow card late in a tense Premier League 2-1 win over relegation-threatened Wolves at Carrow Road.

City's talisman had coolly cancelled out Matt Jarvis' opener before sending Wayne Hennessey the wrong way from the penalty spot after Eggert Jonnson handled Wes Hoolahan's piledriver. Holt was booked just past the hour mark after tangling with Roger Johnson before a lunging tackle from behind on Michael Kightly left City to survive the final onslaught with ten men. Lambert admitted Holt's late challenge always ran the risk of a booking from referee Mark Clattenburg - but the City chief was at a loss to understand the first caution.

'The first one, I don't know what the referee has done there,' said Lambert. 'The second one, I think Grant has won the ball but you run the risk once you go to ground and you have already been booked. I think it is harsh. I've not spoken to him but the first one was for a foul and a free kick on Grant. I still debate the first one. I wasn't sure but someone in the dugout area said, 'I think he has already booked Grant,' but I don't know why he did it.'

Lambert was delighted to ease any lingering relegation fears with a first Premier League win since beating Swansea in mid-February.

'Over the moon to win. It was a massive win for us,' he said. 'Delighted with the team. Proud as anything for what they have done. I thought we deserved to win the game. Wolves are probably the same as Wigan, in the sense of finding it easier to play away from home at the minute. Look at the Wigan result (against Liverpool), it is probably easier for those fighting for their lives. I knew it was going to be a difficult game. It takes a big effort to go and do it and turn it around after they scored first but it shows the effort of the lads. I thought some of the football in the first half was excellent. They adapted to a different system. We went three at the back and I trusted them to do it.'
