Ryan Giggs believes Ole Gunnar Solskjaer needs to sign four or five more players to get Manchester United back where they need to be.
United spent big to recruit Harry Maguire, Aaron Wan-Bissaka and Daniel James during the summer transfer window but have started the season in disappointing fashion and a top-four finish already looks like a pipe dream.
And club great Giggs believes mass recruitment is required to get United playing the way Solskjaer wants them to.
"They need another four or five players," the Wales manager said.
"He (Solskjaer) has bought in three players but he probably needs seven or eight (altogether).
"But you can't do that over one transfer window, so you have to be patient because it will be slow.
"The culture has changed and what he is trying to do was much needed. He needs time."
Solskjaer will lock horns with another former United player, Steve Bruce, when the Reds go to Newcastle on Sunday afternoon looking for their first away win in the Premier League since February.
Newcastle have endured a difficult start to the season of their own but Giggs is backing both Bruce and Solskjaer to ride out their clubs' respective storms.
"I knew Brucey as a player and he was a leader," Giggs said.
"I've also spoken to players who have played for him and they have enjoyed it. It's a tough club, Newcastle.
"When you don't win regularly at big clubs you are going to get criticised. But Brucey and Ole are big enough characters to turn it around, with time and a bit of luck. Every manager needs that."
