Nigel Adkins's side have struggled so far, with just one win from 11 games. Lambert's 11-game record After 11 games in the Championship last season, Rickie Lambert had scored eight goals. This season he has four. Lambert described the Premier League as ruthless and said: "We were all expecting a step up but it has shocked a few of us. It is harder." Speaking to Football Focus, he added: "I think the main thing is that any mistake we make gets punished. It is ruthless.
"The Premier League has the best players in the world and this is where we want to be. "We are learning very fast and have to stop making the errors and score the goals at the other end." Lambert scored over 20 goals in each of the past three seasons for Southampton after joining from Bristol Rovers. He is the club's top scorer this season with four goals, but has not scored since his double helped Southampton to their only win of the season - a 4-1 victory over Aston Villa on 1 September.
"I have definitely noticed the difference," said Lambert. "Every defender is very intelligent, stronger, faster and you get less chances but you still get chances. Saints' Premier League 2012: Southampton have won five points from 11 games this season Saints' only victory came against Aston Villa in September They have the worst defensive record in the league having conceded 29 goals "You still have to be confident that when a chance comes you can put it away."
Southampton head to QPR on Saturday, with manager Adkins coming under increasing pressure to improve results. Lambert believes the former Scunthorpe boss is the right man to turn things around. "I definitely want him to stay," he said. "He looks at me to try and lead the team as well and I am trying obviously to help him. "I understand he is under pressure but it is not nice, it is not his fault. It's all of our fault. "It's little errors that are costing us at the moment but I think some of the performances this season have deserved more points than what we got."
