John Achterberg believes golden glove winner Alisson Becker can improve

Liverpool goalkeeper Alisson Becker delivered an impeccable performance during his debut campaign at the club, but Liverpool's goalkeeping coach John Achterberg feels that there are a couple of areas where Becker needs to improve.

"When you come new into the Premier League, you always need time to settle in, but he picked it up quickly. There were a couple of areas where he needed to adapt, but everything else was automatic. We worked in training on the things that could happen in terms of aggression, players trying to block and things like that, so I think he was well prepared," the club's official website quoted Achterberg, as saying.

Becker clinched the Premier League's Golden Glove after he achieved 21 clean sheets in the top flight. Achterberg is impressed with Becker's performance and stated that there is nothing to complain about. He went on to call the 26-year old 'one of the best in the world'.

"If you have a season like he's just had - and we still have one game to go - it'll be hard to beat. 21 league clean sheets! He had a great season and his level was probably one of the best in the world, so we cannot complain," he said.

Alisson was a key player during the Premier League as the club conceded just 22 goals in 38 outings.

Liverpool will be competing with Tottenham in the Champions League final on June 2.
