It came as Arron Scholes sent a warning to Ajax star Matthijs de Ligt about signing for the club this summer.
Scholes jnr instead told De Ligt to join Barcelona, where he would “enjoy” his career.
“As much as I’d love to see de Ligt at United, I wouldn’t even wish that on him,” the teenager tweeted.
“Go to Barca and enjoy your career mate because we’re w*** and have a team full of b***ends.”
Manchester United, Barcelona and Bayern Munich have all been linked with De Ligt, in a move worth around £70 million.
Ole Gunnar Solskjaer and Ed Woodward are charged with revamping the Red Devils’ struggling squad this summer, whether or not they qualify for the Champions League.
Declan Rice and Jadon Sancho are among those linked to Old Trafford already but Ajax’s stellar campaign has led to speculation over a move for Dutch youngster De Ligt.
The young centre-back has starred in his team’s run to the Champions League semi-finals and Ajax have admitted that he will leave at the end of the season.
However United will probably not be pleased with Arron’s assessment of the situation.
Criticism of this United side has been rife since Solskjaer’s initially strong run of form subsided, not least from the former midfielder Scholes himself.
The 44-year-old is a vocal critic of the direction the club has taken in recent times and wants to see a well thought out transfer policy enacted this summer.
“I think it’s a confusing club and a confusing squad of players at the minute,” Scholes told Premier League Productions.
“I always think at Manchester United and at big clubs, you’re only as good as your centre forwards are and your attacking players.
“I’m not sure whether these attacking players are good enough.
“We talk about potential with [Anthony] Martial, [Marcus] Rashford, but you’re getting to a point now where it’s not potential, you have to start producing week in, week out.”
“[Romelu] Lukaku, I’m not sure if he’s a top class centre forward that’s going to score you 30 goals to win you a league. There’s confusion with the forwards.
“When I played we had four centre-forwards, who were brilliant, and they were centre forwards.
“You look now and you’ve got Lukaku, who’s definitely a centre-forward, but then you’ve got Martial, Rashford, [Alexis] Sanchez. Are they centre-forwards? Are they wide players?
“There’s confusion all over the pitch. A lack of identity.”
