There was no stopping Barca, with both Daniele De Rossi and Kostas Manolas both unfortunate to turn the ball into their own net, ahead of a goal from Gerard Pique.
Barcelona needed some help from their opponents but ultimately ran out 4-1 winners over Roma in their Champions League quarter-final first leg. "No we are not anxious about it", Valverde said, when asked on Saturday about a possible over-reliance.
The Spanish outfit are looking to win their first Champions League title since 2015 when FC Barcelona beat Juventus to win the treble.
What can be said about a performance at the Camp Nou that surprised everyone for its enthusiasm and application but left Roma three goals down halfway through the tie?
"It is a big game against one of the best teams in Europe, if not the best team in Europe at the moment", said Klopp on Tuesday. "It would have been better to not concede but we can not complain, we have got a very good advantage". "We know the quality the team has in attack, but we have improved a lot in defence and the sensations are very good". Busquets is also key to that plan and Barca will be relieved to have him back after he trained on Monday following his recovery from a broken toe.
"Barcelona are unbeaten in their last nine Champions League ties and have conceded only two goals in those games. We have a good lead, and now we need to rest up and prepare for the match against Leganes [on Saturday in La Liga] and then the second leg", Pique told beIN Sports Spain. But no matter - Barca weren't three goals better on the night, but they are better, and save for a miracle at the Stadio Olimpico they are in semifinals. "That's what we want to do and, if we achieve that, then I'm sure we'll make it into the next round".
There was concern for Sergio Busquets, who asked to be withdrawn with a problem on his return from injury.
"The truth is we know that in the game we can and we must improve in several points", Barca's Ivan Rakitic said.
"(Lionel) Messi is reaching incredible levels again and even to stop only him is not easy.
Busquets hasn't played in almost 20 days since hurting his right foot against Chelsea.
However, former Champions League victor Alessio Tacchinardi believes the Italian team have no hope of beating Barca.
"We think he will be fine for Wednesday but we will see how he feels after tonight's effort".
