Barcelona head coach Quique Setien thinks they had their Champions League last-16 second leg against Napoli under perfect control - even though he was feeling nervous on the touchline.

Goals from Clement Lenglet, Lionel Messi and Luis Suarez secured a 3-1 win for Barca at Camp Nou on Saturday and a 4-2 aggregate victory.

Barca were 3-0 up and had another goal through Messi disallowed for handball in the first half, and although Lorenzo Insigne's penalty shortly before the interval gave Napoli some hope, they could not find a way back into the contest against a resilient Blaugrana.

Barca have endured nightmarish second-leg losses to Liverpool and Roma in the past two seasons, so Setien was particularly pleased with the manner of their performance when under pressure from Napoli, even if he could not always keep his anxiety in check.

"It was what we were looking for, to take the first step and to wait for the rest of the games with the same excitement with which we faced this one," he told Movistar.

"We were very good and we deserved the victory.

"It's true they had us compromised in the opening minutes. Napoli are a really good team - it's not easy to do what we've done. They're one of the best teams in Italy.

"We controlled it perfectly, we had a really good first half and in the second they were more in charge but they still didn't put us in much danger.

"A second goal would have given them a boost that could have threatened us. It's normal to be a little bit nervous, of course."

Messi took a heavy kick to his calf in winning a penalty against Kalidou Koulibaly, but Setien is confident he will be fit to face Bayern Munich, who destroyed Chelsea 7-1 on aggregate, in next week's quarter-final.

"He took a strong hit, but he looks okay. It'll need treatment but I don't think it'll be a problem," he said of Messi.

"It'll be a really tough game. They have gone through a tie with a six-goal margin. They are an amazing team and it'll be a great game."
