Liverpool coach John Achterberg has many positive things to say about the club's no.1 goalkeeper Alisson Becker.

The Brazilian joined last summer from the Reds on the back of high profile howlers from their top two keepers the previous season.

He came in and immediately showed his quality, with the club winning the Champions League in his first campaign.

And coach Achterberg believes Alisson's presence has made the Anfield crowd positive about the team's defence.

"I was convinced that if we are going to spend money then Alisson was the No.1 I would sign," he told the Liverpool Echo.

"Obviously what he has done up to now, it has worked out. You're looking around at the way we play and his movements and you have to say he is the No.1.

"Looking at Premier League level, he has worked out this move himself with the qualities he has shown over the years. Obviously these moves need to come off, because you look at David de Gea (at Manchester United), it took one or two years before he was at his level and had the trust.

"He only came back into the Manchester United side because the other goalkeeper got injured.

"So you don't have a lot of time to settle because the talking is there all the time and I think Ali and the boss have changed the way the crowd are really with the way they manage and play. Now the crowd is positive from the first second and are not worried if the ball is in the air or the box."
