Barcelona manager Pep Guardiola has admitted that his side may regret not scoring an away goal against AC Milan in the first leg of their Champions League quarter-final.
Despite controlling most of the match, the Catalan giants failed to breach the Milan defence and the Italians will head to the Nou Camp in a positive position after the goalless draw.
Guardiola said: "We knew Milan's quality and not scoring in the away leg is a bit damaging for us."
The Spaniard was also disappointed with the playing surface in Milan.
"It is always a pleasure to play at San Siro. It's just a shame that this pitch is not suited to a football match. Inter and Milan both deserve a better playing surface," Guardiola added.
Defender Carles Puyol was critical of the referee following the match.
