The Real Madrid star has been linked with a move, and despite being positive, Wilkins says there is one negative to his game.
The defender is currently in negotiations with current club Real Madrid about a new deal but they have so far failed to come to an agreement, with both parties seemingly some distance apart.
That has led to speculation that the Spaniard may leave the club, with Manchester United reportedly telling Madrid to give them Ramos in exchange for goalkeeper David de Gea, according to the Guardian.
And while he concedes the move would be a good one for United, Wilkins does warn them about Ramos’ poor disciplinary record.
“Sergio Ramos has been around the block and he knows the score, especially in Champions League,” he said.
“He’s a red card walking though. He gets het-up when things don’t quite go his way. It would be an interesting signing because the first year is always difficult when you come to the Premier League.”
Despite having won everything with club and country, and being one of the top defenders in world football, it is Ramos' disciplinary record that garners the most attention.
Since joining Madrid, he has been sent off a staggering 19 times, which also happens to make him the most red carded defender in the history of La Liga, and while his quality is undoubted, that recklessness does make him something of a liability.
The good news for Manchester United however, is that he wasn’t sent off all of last season, suggesting he may have finally curbed that part of his game once and for all.
