The Anfield hero, who now works alongside former Red Devils’ captain Gary Neville on Sky Sports, believes the criticism from some sections of the United support has been extremely harsh and underserved.
Carragher makes the point that, while Ramos might be prone to making the odd mistake now and again, Real Madrid have stuck by the hugely successful World Cup winner for a reason.
It’s understood that Manchester United are attempting to sign Ramos as part of the deal which will see wantaway goalkeeper David de Gea move in the opposite direction.
Ramos’s relationship with Real Madrid has deteriorated rapidly over recent weeks - and it’s now believed the 29-year-old Spain international is ready to leave the Bernabeu following 10 years at the club.
Carragher angered by criticism of Ramos
Some United fans are less than enamoured by the prospect of signing Ramos, who has been sent off more times than any other player in Real Madrid’s history, but Carragher is infuriated by the unfair criticism directed towards the world-class defender.
“I get a bit wound up by the criticism Ramos gets,” Carragher told talkSPORT. “This is a fella who has won everything, he plays for one of the best clubs in the world and one of the best international sides we’ve ever seen.
“He is rash at times, he has moments of madness and does get overly emotional in games, that’s always been a problem for him, but let’s not forget that it’s a problem for Wayne Rooney as well.
"I’m not bothered about whether United sign him or not, or whether he’d be a good signing or not, but if he is not rated as one of the world’s best players, who is?
“If his trophy record doesn’t give him a bit of credit, what chance have I, or any of the centre-backs in the Premier League, got? I think it’s disrespectful – he’s won nearly 130 caps for Spain! He’s not playing for Mickey Mouse teams.
“I’ve heard callers say he hasn’t reacted well under pressure and he makes mistakes – what defender doesn’t make mistakes?
“If a team like Real Madrid could find a better defender, they would, but they don’t. Ramos plays every week, they win everything and people still chip away at him and criticise him.
“Top class centre-backs are a dying breed now, there’s very few now compare to years ago. If United don’t get Ramos, or don’t want to sign him, who else would they get?”
Ramos: More successful than Hummels and Otamendi
It seems that either Borussia Dortmund captain Mats Hummels or Valencia’s Nicolas Otamendi would be more popular signings in the eyes of most Manchester United supporters, despite the fact Ramos has won more than the pair of them combined throughout his career.
Ramos has also scored more goals than Hummels and Otamendi combined. The Real Madrid centre-back has found the back of the net 58 times in his career to date, making him a real attacking threat from set-pieces.
Although it’s far from the most important attribute for a centre-back, it’s still a useful asset to have - and potentially one of the reasons Louis van Gaal is so keen to bring him to Old Trafford.
Ramos would be an excellent signing for United
Ramos might not be everyone’s cup of tea because of his on-pitch personality, but he’s a born winner who relishes the big occasions. He steps up when it matters most, too, as everyone witness at the 2014 Champions League final in Lisbon.
Without Ramos, there’s every chance Real Madrid would still be waiting to win La Decima; the Spaniard’s last-gasp headed equaliser against local rivals sent the match to extra-time, during which Los Blancos went on to record a 4-1 win.
Real Madrid president Florentino Perez ought to be eternally grateful to Ramos for a moment that will go down in the club’s history as one of the most important, but the relationship between the two men has soured.
Of course, Ramos might be using Manchester United’s interest to negotiate a better contract at Real Madrid - there are plenty of suspicions from those in the know that this is the case - but it will be fascinating to see how the situation develops over the forthcoming days.
