Paul Scholes recently called Robbie Savage a "knobhead" on live TV but he has launched a more serious and damaging attack today.
The former Manchester United midfielder says the club's style of play under Louis van Gaal is 'miserable' and goes against the attacking traditions held by the club.
Scholes has offered the latest criticism to Van Gaal's tactics after West Ham manager Sam Allardyce called the team 'long-ball United' which provoked a bizarre dossier-led defence from the Dutchman.
The former England midfielder wrote in the Independent: "At the moment I'm struggling to watch Van Gaal's team with any great enjoyment.
"At times, Manchester United's football is miserable.To beat opposing teams you have to attack, and to attack you have to take risks. Too few of the players in the current team are prepared to take those risks."
Despite the uninspiring performances this season, United sit third in the Premier League after Wednesday's 3 - 1 win against Burnley, a display van Gaal conceded he 'didn't like'.
Scholes, who won 11 Premier League titles with the Red Devils, has compared the team's current style with that employed by his former manager Sir Alex Ferguson.
"In the periods of my career when I stopped passing the ball forward, or when I stopped looking for the risky pass that might open up a defence, the consequences were the same. The manager stopped picking me.
"I got back into the team when I went back to doing it the way he wanted.
"United's history was built on attacking football, which does not always mean that the team kept clean sheets or did not concede chances.
"Why do you think United have had some of the best goalkeepers in the world over the years? They needed them because the team committed so many players forward."
