Liverpool keeper Loris Karius received plenty of criticism over the past two weekends after mistakes cost his side points.
Gary and Phil Neville, along with Jamie Carragher were particularly vocal in their criticism of the player.
Carragher, on Sky Sports at half time during Liverpool's 2-2 draw with West Ham at the weekend, told Karius told that he needed to 'keep his mouth shut and do your job'. This was regarding an interview with the Daily Mail's Ian Ladyman in which the keeper said he 'didn't care what Gary Neville said'. This was a sentiment reiterated by Phil Neville later in the evening on Match of the Day 2.
Didi Hamann subsequently came out in defence of his fellow countryman, getting into a Twitter argument with Carragher regarding his comments.
Hamann was a guest on the latest episode of Eamon Dunphy's podcast 'The Stand' and addressed his 'tussle' with his former teammate. He also called Phil Neville defending his brother 'childish'.
It was a Twitter tussle, not a war. You've not seen me go to war.
The defence I took for the goalkeeper was because of the way they spoke about him. I think the choice of words was wrong. They told him to get on with things. It's not a problem, it's their job.
For Phil Neville to defend what his brother said about his the keeper was just childish. You can't tell an adult to shut up. It's not what you do. The guy deserves respect, whether he's good enough to be a goalkeeper in the Premier League, I don't know. He's got ability. Has he got the mental ability? I'm not sure.
I just felt the choice of words was wrong. We've got to be careful about the way we talk about these players.
Hamann added that he has also been a critic of Karius's performances but it was the choice of words from the Nevilles and Carragher which particularly annoyed him.
A lot of it is down to confidence at the moment. His confidence is pretty low at the moment. He doesn't instil a lot of confidence into his back four because he's too worried about his own performance. He made a couple of mistakes at Bournemouth in the last few mintues. The free kick against West Ham, he's got to do better. There's a couple of mistakes he's made, there's no denying it. He cost his team goals.
It wasn't about the criticism he faced because I criticised him myself. It was about the choice of words.
