Sergio Romero has a history Manchester United fans should be wary of

Manchester United 3

Manchester United fans may be celebrating the free signing of Sergio Romero but the goalkeeper is prone to crazy behaviour and Louis van Gaal knows this.

It’s just over 15 years since Fabian Barthez brought his unique brand of crazy to Old Trafford but, in Sergio Romero, Manchester United may have found the Frenchman’s heir apparent.

Like Barthez, the Argentine carries plenty in the way of international pedigree – he appeared for La Albiceleste in the World Cup and Copa America.

And like Barthez, he’s prone to what can only be described as a erratic behaviour and though the Gallic ‘keeper combined these moments of madness with some great saves, we are not so sure about Romero.

A story from back in 2009 illustrates just what the South American shot-stopper is capable of and why Manchester United fans should be a little concerned.

Back then Romero was a young goalkeeper with AZ Alkmaar in Holland.

Having broken into the first team, the Argentine found himself in goal for an important Dutch Cup quarter-final in the 2008/09 season.

Leading NAC Breda 1-0 through an early goal from future Tottenham star Mousa Dembele, Romero was guilty of letting a tame shot from Nourdin Boukhari slip through his grasp.

NAC went on to win 2-1 with the Argentine coming in for criticism from all corners.

But things were made a whole lot worse in the aftermath of the game after Romero punched both a door and wall, resulting in broken bones in his hand.

Out of action for eight weeks as a result, the incident should have served as a warning to Louis van Gaal, after all he was the manager at AZ back then.

But rather than blame Romero too much, LVG pointed to the “Argentinean temperament” as the root cause of the problem in quotes republished by

“His anger was not about the defeat or our cup exit but because his blunder had such an influence,” he explained. “He cried afterwards and apologised to me."

Though it’s been six years since the incident in question, with high-pressure games to come in the Premier League and Champions League this season, Manchester United fans may be a little less happy about Romero’s arrival now.
