Jurgen Klopp has launched a passionate defence of Liverpool goalkeeper coach John Achterberg.
Achterberg joined Liverpool as the goalkeeping coach of their reserve and academy teams in 2009.
He was promoted to the same role with the first team in 2011, thereby coinciding with a difficult period for goalkeepers at Anfield.
Pepe Reina, Brad Jones, Simon Mignolet and Loris Karius have all struggled during their time working with the Dutchman, which many are reluctant to write off as mere coincidence.
Achterberg gave a rare interview after the Champions League final, in which Karius made two high-profile mistakes in defeat to Real Madrid.
That led to yet more criticism, and Klopp has been forced to defend his coach.
“First of all, John is a goalkeeper maniac. He’s working constantly,” Klopp told the Liverpool Echo.
“It’s so easy. All the people in the pubs think they know and understand football 100%.
“But if you asked them: ‘What does a goalkeeper do?’ They couldn’t say more than ‘catch balls’. They have no clue about goalkeeper techniques and all that stuff.
“John is the first in the building and the last to leave. No matter how early I get into Melwood, I get up the stairs and he’s already there – sat there with the laptop open watching goalkeepers from the other end of the world.
“He’s constantly in there developing, changing training programmes, working with the boys. For me, he’s a fantastic goalkeeper coach.
“There’s not any reason for criticism. He’s also a fantastic lad.
“I can understand that people are like this – if they haven’t been happy with goalkeepers in the last few years that they think John is the reason for it.
“For sure, that’s not the case. Liverpool is a difficult goalkeeper place or hopefully it was a difficult goalkeeper place.
“Now we have found a solution that everyone is happy with – a fantastic goalkeeper.
“We are really happy in this moment and now we have to perform.”
