Barcelona playmaker, Lionel Messi missed the 13th penalty of his career during the 2-1 UEFA Champions League win over Manchester City at the Ethihad stadium.
Luis Suarez’s two first half goals gave Barcelona a 2-0 lead before Sergio Aguero pulled one back for the hosts.
Man City number one, Joe Hart then saved a decisive penalty from Messi with virtually the last kick of the last-16 first-leg match.
However, Aguero insists that the tie is “unfinished”, with City set to travel to the Camp Nou for the return leg on March 18.
The Premier League champions who face an uphill task to reach the Champions League quarter-finals for the first time will clash with Liverpool when the Premiership resumes at the weekend.
Man City manager, Manuel Pellegrini is adamant his team approached the first leg in the correct manner.
When asked if he harboured any regrets over City’s set-up, Pellegrini replied: “No, I was very happy. It was the way we must play against Barcelona.
