Manchester United's Casemiro has hit back at the 'disrespectful' criticisms over his performances this season.

The Brazilian midfielder has come under fire in recent weeks after struggling for the Red Devils - with his performance against Arsenal being particularly scrutinized.

He was also recently told by Jamie Carragher to 'call it a day' and move to Saudi Arabia or the MLS after his disappointing display against Crystal Palace. 

However, the former Real Madrid star clearly has a different perspective on things as he hit back at critics during a recent interview with Sky Sports. 

The Brazilian said: 'I was considered one of the best signings of the Premier League last season, and now I'm not worth anything anymore?

Man United midfielder has labelled the criticism over his performances as 'disrespectful'

'The criticism is disrespectful. So when it's lacking respect, then it's worrying, and I don't have to respect that either'.

Against Palace, Erik ten Hag's men suffered their heaviest loss of the season as Casemiro deputised at centre back for an injury-hit Man United.

However, his display at the back left a lot to be desired and Sky Sports pundit Carragher lamented the Brazilian's performance. 

'I said at half-time he's (Ten Hag) got to bring Casemiro off,' Carragher said.

'I know he's got kids on the bench but I think Casemiro, deadly serious, should know himself tonight as an experienced player that he should only have another three games left at the top level. The next two league games and the [FA] cup final. 

'And he should be thinking "I need to go to the MLS or Saudi". I'm deadly serious. He's aging, the people around him they need to tell him this has to stop.

'We are watching one of the greats of the modern time playing in one of the best midfields we've seen who dominated Europe. 

'Him holding, [Toni] Kroos to one side [Luka] Modric to the other was one of the best midfields. Could easily go up against the Barcelona midfield we all loved (with) [Sergio] Busquets, Xavi and [Andres] Iniesta. 

'He's been an absolute great. I am nowhere near on a level of what that man has achieved. Champions Leagues, playing for Brazil, playing for Real Madrid. 

'But I always remember something when I retired myself, there was a saying I always  remember as a footballer, "leave the football before the football leaves you". 

'The football has left him at this top level he needs to call it a day at this level of football and move.'
