Manchester City equaled their best ever away win in Europe on Tuesday night with an impressive 3-0 win at Czech side Viktoria Plzen.
Manuel Pellegrini's team looked sluggish in the first half and failed to break the deadlock until after the break when three goals in ten minutes left the opposition with no reply.
There was an emphatic performance from Argentine striker Sergio Aguero, who helped set up Edin Dzeko for the first goal and scored another himself.
City will face reiging European champions Bayern Munich at the Etihad Stadium in the next game in Group D and former City midfielder Dietmar Hamann told Sky Sports he expects great things from Manchester club.
"I think City can be a threat to the very best in the Champions League. On their day they are as good as anyone in the competition.
"In the first half they passed the ball quicker and they didn't try to play these balls over the top - these hopeful balls that most of the time, were hopeless. Fernandinho played a couple towards the end of the first half and it was getting a bit edgy and agitated."
"In the second half they were more patient. The goal helped, it settled them down and they played with more fluency and confidence, it was a completely different team.
"They played the second half how you expect to see Real Madrid, Bayern Munich or even Barcelona dismantle a limited side.
"This is how they have to set the bar now, this is the standard they have to be and they have to kick on now, because this team is capable of beating any team in the competition, I'm sure about that. It was only Plzen today, but they've gained confidence and should be better for it."
Champions League Goals pundit Dietmar Hamann, who won the Champions League with Liverpool in 2005, believes Sergio Aguero is on of the top forwards in Europe.
"There are lot of good players in the Champions League, but if you look at centre forwards he's right up there. I think the goal proved it, he also hit the woodwork in the first half and he did tremendously well to set up the first goal for Dzeko."
Must beat Bayern
"If you look at the strength of their squad and their bench - which is missing David Silva and a few others - they can go out and beat anyone.
"They need to get out of the group and if they beat Bayern Munch they will take a big step towards that because they will beat Plzen at home.
"Once they reach the knockout stages I think Man City will be the team that nobody wants to play against because going forward they've got plenty of talent and with Kompany back the defence looks a lot more assured than it did before."
