Frank Lampard believes Man City should be a little disappointed with their Champions League performances in recent years, but he's backed the "forward thinking" club for European glory sooner rather than later.
Lampard made the controversial loan move to Man City from New York earlier this season after leaving Chelsea last summer when he wasn't offered a new contract.
The former England international is now ready to help City achieve their own Champions League dreams having lifted the trophy with Chelsea in 2012.
I think maybe Man City would be disappointed in recent years where they have got to the Champions League but for me it is coming, it’s a club that is forward thinking so I think that in England we should be proud that we have got teams that are always getting to these later stages of the Champions League and I think that Manchester City can.
I can feel it in the club and we are certainly aware about what a big game it is that it’s a situation where we want to take it on and we want to show that you can get past Barcelona and try and advance all the way to the final.
