Manchester City striker Sergio Aguero has no doubt the club are destined for more titles.

City's second Champions League campaign began with a dramatic last-gasp 3-2 defeat to Real Madrid at the Bernabeu Stadium last night.

Aguero, who was linked with the Spanish champions last season, watched a pulsating encounter unfold from the bench as an unused substitute and is convinced City will bounce back.

The former Atletico Madrid player tweeted after the game: "I feel comfortable and appreciated in MCFC - it's a project I feel involved in. We want more titles and we'll get them!"

And to underline his commitment to the club after returning to a city where he is always the subject of press interest, he added: "Just to make it clear - I'm very happy to be in MCFC. It's the best decision I could have taken."

Aguero, 24, scored 30 goals for City last season after joining the Barclays Premier League champions in a £38million club record deal.

He is yet to make an impression this season having suffered a knee injury in the opening Premier League fixture against Southampton last month.

He had hoped to make his return in the Spanish capital but events prevented manager Roberto Mancini bringing him on.

Mancini said: "I had two players injured, (Samir) Nasri and Maicon. I wanted to play Aguero in the last 20 minutes."

City were beaten in a remarkable finish as Karim Benzema and Cristiano Ronaldo struck for Real Madrid in the last three minutes.

Aleksandar Kolarov had looked to have snatched an unlikely win when his free-kick bounced through the area to find the net six minutes from time.

Edin Dzeko and Marcelo had earlier traded goals after the hosts had dominated the first hour.

The result leaves City playing catch-up in a tough-looking Group D that also includes Borussia Dortmund - also winners on the opening night - and Ajax.

Mancini said: "I think other teams will lose here. Now we have five games and it is important we beat Dortmund next game at home.

"We know it will be difficult playing against a top team but this year we want to go through."

City failed to get beyond the group stage in their first Champions League campaign last year.

Captain Vincent Kompany tweeted: "Thanks to the huge number of travelling fans. This game will give us the desire to improve again. Eventually we will get there."
