Manuel Pellegrini aims to get one over on old nemesis Pep Guardiola

Manuel Pellegrini's record against Pep Guardiola is a sorry one but he gets another chance to finally put one over his tormentor when Manchester City host holders Bayern Munich in the Champions League tonight.

During his time in La Liga, the Chilean was in the opposing dugout to former Barcelona coach Guardiola on eight occasions and only avoided defeat once when his Villarreal side drew 3-3 in the Nou Camp in the 2008-09 season.

His brief stay at Real Madrid included two Clasico defeats by Guardiola's Barca and the trend continued at Malaga, where he soaked up another four losses against the Catalans.

The furniture has been re-arranged in European soccer, however, and Pellegrini will feel his expensively assembled side will start as equals to Bayern, who have yet to spark under Guardiola, though unbeaten.

Pellegrini was head-hunted by City at the end of last season partly because of his tactical nous in the Champions League in which he had Villarreal and Malaga punching above their weight.

He has never failed to survive the group stage in his previous Champions League campaigns and City's opening-day, 3-0 win away to Viktoria Plzen has raised hopes that they can finally make their mark on the competition having twice fallen short of the knockout rounds.

But Pellegrini's opening weeks in charge of City have been far from smooth with two defeats in their opening six Premier League games, the latest a 3-2 loss at Aston Villa last Saturday. "It's always better to play in the Champions League when you have won the Premier League game before but the team are playing with trust and confidence so I hope we can [play] a good match again [tonight]," he said.

"In general, I was very happy with the way we played."

City could be boosted by the return of midfielder David Silva, who has been out since the end of August.

Guardiola's start at treble-winning Bayern has been efficient rather than spectacular with last Saturday's 1-0 win at home to VfL Wolfsburg indicative of their form so far.

"It is very difficult at this moment to improve with Bayern because they won the [treble - Bundesliga. German Cup and Champions League]] but he will find a way because he is a very good manager," Pellegrini, who does not have that dilemma at City, said.

Bayern began the defence of their European crown with a 3-0 home win against CSKA Moscow and there are already signs that the Bundesliga giants are playing a more intricate, possession-based game than under the more direct Jupp Heynkes.

Against CSKA Bayern completed 753 passes, more than any other team in the opening group games, and Bayern are unlikely to change that blueprint throughout the campaign, even if Guardiola admits his side have room for improvement.

"We need to do some things better even though we won against Wolfsburg," Guardiola said. "I am certain we will put in a good performance against City."
