MAURICIO Pellegrino is adamant unbeaten Premier League leaders Manchester City can be defeated.

Ahead of Saints’ trip to the Etihad Stadium on Wednesday night, the Argentine boss says he’s going to set his team up to test Pep Guardiola’s irrepressible side, who are cruising at the summit right now.

City are undefeated after 13 games and eight points clear at the top of the Prem, having netted an impressive 42 goals along the way.

But Saints are bouncing after their 4-1 defeat of Everton at St Mary’s and, with City only narrowly beating Huddersfield 2-1 on Sunday, Pellegrino has urged his side to give it a go and “be at the top of our game”.

“Nobody is unbeatable. Every single team have problems. Yesterday, Huddersfield were really close to getting something,” he said.

“It’s going to be tough for us. We need another good game because we play against one of the best sides in the Premier League.

“We need to be 100 per cent with our performance, our attitude. We have to be at the top of our game.”

Pellegrino is relishing the challenge at the Etihad and has a clean bill of health, with no new injury problems ahead of this one.

Defensive midfielder Oriol Romeu is back available after serving a one-game suspension against Everton, while Mario Lemina should be fit enough to start after a substitute appearance against the Toffees.

“It’s incredible how they can sustain their performance in every single game in Champions League, playing most of them with the same players,” said Pellegrino about City.

“Okay, to be a top team, the first thing you need is to create a mentality to do and that’s something that is not easy, but they are now in an amazing moment.

“Our challenge is to now play against this side and play better than we were against Liverpool.

“Against, these teams they don't need too many chances to score goals.

“We will try. It’s another opportunity and I think my players are much better than before. Hopefully it’ll be a nice day for us.”

The 46-year-old manager is hoping that the 4-1 victory last time out will give the players the confidence to go and give a good account of themselves at City.

“I don’t know any manager who doesn’t want to score goals. But sometimes in football you have something amazing and you score four goals,” he said. “But we couldn’t score many in the past but hopefully this game can help us to play with more confidence, especially the games at home when I think we deserve more.”
