Manchester City captain Vincent Kompany rued another red card as his side were dumped out of the Champions League by Barcelona.
Goals from Lionel Messi and Dani Alves sealed the victory, 4-1 on aggregate, while Kompany scored a consolation goal as his side failed to deal with being reduced to 10 men.
Pablo Zabaleta was shown a second yellow card when protesting to referee Stephane Lannoy after Edin Dzeko was brought down by Gerard Pique in the box.
Speaking at a post-match press conference, Kompany admitted this changed the game but said he believes the defeat will help City to come back stronger, according to The Telegraph's Thom Gibbs:
I think I can speak for the team and say that we have nothing left in the tank, we have given everything. We had chances and you have to take those chances. Over the course of the two games, whenever we had 11 players there wasn't much between the two teams.
Obviously Messi is an incredible player and whenever he has the ball there is a danger but away from that we matched them. If we had scored one of those chances it would have been a completely different game.
This should motivate us, it's only our third season in the Champions League and I don't think we need to fear anyone. Every team has its day, and our day will come.
City travelled to Camp Nou looking to overturn a two-goal deficit after succumbing to strikes from Lionel Messi and Dani Alves at the City of Manchester Stadium in a match that also saw Martin Demichelis sent off.
Going into the game on the back of an FA Cup exit to Wigan, City had to make changes in order to rise to the challenge of taking on Barcelona, captain Vincent Kompany recognised. He tweeted:
City had two excellent chances to take the lead at the Camp Nou, with Samir Nasri ending a flowing move but unable to divert past Valdes, and Pablo Zabaleta also rifling his left-footed shot just wide of the upright.
Despite all of the Citizens' pressure, Barcelona took the lead, thanks to a delightful chip from Lionel Messi. Joleon Lescott failed to deal with a through ball that deflected off the defender and into the path of the unrelenting Messi:
Messi's magic had been troubling City's back four throughout the second-leg match, as Lescott struggled to deal with the Argentinian's pace when he burst through the Citizens' defence on a number of occasions.
Daily Mirror chief sports writer Oliver Holt tweeted about Messi's performance and his goal that required City to score three to advance to the next round:
City had looked set for a penalty after Edin Dzeko was fouled in the box by Gerard Pique, however protests were waived away. As Zabaleta continuously complained to the referee, he was shown a second yellow to see his night curtailed.
Kompany scored a late goal as he bundled in Edin Dzeko's header to give his side a consolation and travelling City fans something to shout about at Camp Nou.
However, the game wasn't finished there, as Dani Alves netted a late winner for Barcelona to seal a 4-1 aggregate win to see Martino's side safely through to the next round.
A spirited performance by a plucky City side, who now have just the Premier League title to focus on as they chase a domestic double following their Capital One Cup win earlier in the season.
Two potential silverware wins in just Manuel Pellegrini's first year in charge may still leave City fans wishing they had more defenders who matched the quality of Kompany.
