A former Manchester United star has now sent the club a warning regarding one of its newest signings.
Dwight Yorke has revealed the reasons as to why he is sceptical about new Red Devils attacker Joshua Zirkzee, who was signed from Bologna for a reported fee of £36.5 million (about R861 million) earlier this month.

The Dutchman has signed a five-year contract with the Premier League side, with the option to extend it by another year, on the back of a 2023/24 campaign that saw him accumulate 12 goals and seven assists in 37 appearances across all competitions for the Serie A club.
The 23-year-old also helped his side secure a spot in this season's UEFA Champions League campaign with their fifth-place finish in the Italian top flight.
Zirkzee was included in the Netherlands squad that competed at the 2024 UEFA European Championship, but made just two substitute appearances at the tournament in Germany.
According to Yorke, who won three league titles during his time at Old Trafford, the Dutch forward's lack of involvement to date for his national team should be a "red flag" to those at United.
"You've got Joshua Zirkzee, who seems to have a decent season with Bologna and could make an impact, but you have to ask why he is not a starter for Holland," the ex-United striker said, per Sportskeeda.
"That's a red flag for me when you come in at United for that sort of fee.
"In recent years, the club have brought in middle-of-the-road players rather than the creme de la creme players that they should be getting.
"United should be signing the very best players in Holland and the best players in whatever national team they are playing for.
"United are not in the position to do that anymore and it worries me."

Yorke, however, went on to add that the newly-signed forward should only be judged come the end of the coming campaign.
"I'm not saying the kid is not a good player. I'm not saying that he definitely can't go and light up the Premier League, but why is he not playing in the Holland first team?" he added.
"Is he great for Bologna, but he's not good for the Holland national team?
"Does that mean he can't be that great for United? But we can only judge him on that at the end of the season."
