Barcelona forward Luis Suarez said he would have perhaps liked to have taken a bigger advantage in the tie, although his side had to be happy after winning 2-1 at Manchester City in Tuesday's Champions League last-16 first leg.
Suarez scored just once in six games against City during his time at Liverpool, but had two inside the opening 31 minutes as the visitors completely controlled the opening half.
City improved after the break and Sergio Aguero pulled one back, however the English champions seemed completely out of the tie after left-back Gael Clichy was sent off for two yellow cards, and blaugrana talisman Lionel Messi was awarded a penalty in added time.
Messi's spot kick was saved by City keeper Joe Hart, and the Argentine headed the rebound wide, leading the Uruguay international to tell Catalan station TV3 directly after the game that his side's one-goal lead ahead of the second leg was perhaps a bit short.
"Sometimes penalties are missed," he said. "We would have liked a bigger lead. In the first half we had a lot of chances, and we could have scored more goals. In the second half they began stronger, and the goal put them back in the game.
"But we know that Manchester City are a great team with a lot of potential, and that they could make it difficult for us. They reacted and it was difficult."
Suarez, who was booed at times by City fans who remembered his controversial three-plus years in the Premier League, said he had enjoyed his return to England.
"It is always special to play these type of games," he said. "Even more for the years when I was a Liverpool player, and was in England."
Suarez suggested that Barca would set out to dominate the game in the second leg at the Camp Nou on March 18.
"The tie remains very open," he said. "We are aware that it is going to be a difficult game, but we will go out to play at the Camp Nou. We must show that we are Barca playing at home. We know we will be playing at home, and must show who we are."
