Barcelona: There was a huge sense of relief in Barcelona after brushing aside their recent Champions League quarter-final failures by beating Manchester United, but Lionel Messi still criticised his sideâs shaky start to the game.
Barca conceded two early chances in Tuesdayâs second leg before Messi set them on their way to a comfortable 3-0 victory with two quick-fire strikes before Philippe Coutinho scored to make it 4-0 on aggregate.
United forward Marcus Rashford rattled the bar in the second minute and then hit a tame shot at goalkeeper Marc-Andre ter Stegen, while Scott McTominay burst into the area but lost control of the ball before he could shoot.
Barca had suffered a humiliating quarter-final exit at AS Roma last year after conceding early goals and Messi urged his team mates to show more concentration in their next European outing, warning that other sides might not be so forgiving.
That message is even more pertinent as Barcaâs semi-final opponents are likely to be Liverpool, who hold a 2-0 lead in their quarter-final tie with Porto and have a reputation for overwhelming teams early on.
âWe cannot start like this in any Champions League game,â Messi told reporters.
âWe said that from the start, we had the experience of Roma, you canât afford to make life hard for yourself because one mistake can knock you out of this competition. We have to be aware of that.â
After surviving the early scares, Barca exhibited their new-found defensive steel and earned a third clean sheet in four Champions League knockout games.
âWe have become much more solid, over the season we struggled a little bit at the back but the whole team is making a huge effort and that makes it far harder for opponents to attack us,â Messi added.
Barca have not won Europeâs biggest prize since 2015 despite dominating the domestic scene in Spain and have had to look on enviously as arch-rivals Real Madrid romped to three consecutive Champions League triumphs.
But there is now a sense in the Spanish media that everything is falling into place for Barca to reach the final at Atletico Madridâs Wanda Metropolitano stadium in the Spanish capital on June 1.
âThis is the year,â proclaimed Barcelona-based newspaper Sport, while Marca said âMessi flies towards the Wandaâ.
âWe had been three years without making the semi-finals but we didnât have any negative feelings. We knew we had a good scoreline, weâre happy to be in the semis but we must continue.â
