Pep Guardiola praises Man City hat-trick hero Raheem Sterling but 'wants more' from Riyad Mahrez

Pep Guardiola "wants more" from Manchester City winger Riyad Mahrez, calling him "a little bit weak" in his work when competing for duels.

Mahrez ended a run of seven straight games of scoring against Norwich on Saturday, but his side ran out convincing 4-0 winners with Raheem Sterling ending his run of five games without a goal by netting a hat-trick.

Mahrez, who was on the fringes of the game at Carrow Road, is out on his own as the club's top scorer this season with 16 in all competitions, but his manager Guardiola feels the 30-year-old can do more.

"He is an exceptional player but I want more," Guardiola told Sky Sports.

"He's clever, he's a goalscorer. But sometimes I want more. Sometimes he's a little bit weak in the duels. We've known each other a long time and he knows the intentions we say to him is in a positive way."

Sterling stole the limelight in the 4-0 victory, scoring a perfect hat-trick. His treble takes his tally to eight goals in his last eight appearances against Norwich and he now has 10 goals in total in the Premier League this season. In total, he has now scored 115 goals under Guardiola at City - only Sergio Aguero and Lionel Messi have scored more for the manager.

"It's a brilliant first goal," Guardiola said of Sterling's contribution.

"The second one was there and you realise after the goal how confident he is, aggressive. In the last game he made an excellent action against Brentford to win the penalty. He is a guy that always creates something."

The City machine are now unbeaten in their last 15 Premier League games, winning 14 of those as they power towards retaining their title. The win over Norwich took them back 12 points clear of Liverpool, who play on Sunday at Burnley.

"We did a really good performance overall," Guardiola said.

"We arrived here against a team in their best moment of the season who are confident that's why it's an important result. How we behaved today is Manchester City. The team is alive, that is the most important thing. We know the rival we have. Liverpool aren't going to drop many points due to the quality and depth of their squad. It's the best squad they've had in the last decade. And we will have to win a lot of games.

"This is an important step - we did our job."

Smith: Poor defending cost us

Norwich boss Dean Smith was left frustrated with his team's defending for all of Manchester City's goals.

"A tough night, I'm frustrated with the manner of the goals we conceded," he said.

"We can't legislate for mistakes, they happen. We stayed in the game and had a couple of chances ourselves.

"The moments were few and far between against a team that control possession really well but the second goal probably killed the game for me, it flattened the atmosphere.

"It was just a poor goal to concede and a poor time to concede it as well. We felt at 1-0 we would get more opportunities in the second half and you have to stay in these games as long as you can."

Smith also bemoaned the decision by referee Andre Marriner to award City a "pathetic" penalty in the closing stages as substitute James McAtee went down in the box.

"It is never a penalty, and I told Andre afterwards it was a pathetic decision.

"That has never been a penalty, it does not seem to bother the officials to give penalties at 3-0."
