Former Manchester City and Bolton midfielder Didi Hamann insists Louis van Gaal doesn't need £200 million to revive Manchester United's fortunes.
The Dutchman is expected to be named as David Moyes' long-term successor next week, with veteran player Ryan Giggs in charge until the end of the season.
Manchester United are expected to be busy in the summer window following a disastrous season in which they are guaranteed their lowest finish and points total in the Premier League era.
Van Gaal is already said to have made Manchester United officials aware of his transfer targets, with Thomas Muller, Marco Reus, Arjen Robben and Toni Kroos all said to be on his hitlist.
However Hamann, who now works as a television pundit, believes the Red Devils needn't go out and splash the cash this summer.
He told TalkSPORT: “I don’t think they need wholesale changes. I don’t think they need to spend £200m on eight or ten players.
“If they bring in three or four quality players they’ve got a chance next season. It’s about getting the best out of players, which David Moyes obviously has not done. That’s the first, biggest and only job to do.
Opinion is split over whether Van Gaal is the right man to take over from Moyes, who was sacked just 10 months after taking charge following Sir Alex Ferguson's retirement last year.
However Hamann is convinced the 62-year-old is up for the job.
“The people I’ve spoken to have said that, in footballing terms, he is one of the best," he continued. He’s a shrewd man and a tactician and he improves players, and that’s a key thing. People forget they’ve got some very talented young players and he’ll improve them, which is almost as important as winning matches because they are the future of Manchester United.
“Everywhere he’s been he’s been successful. You’re not the manager of Ajax, Barcelona, Bayern Munich, the Dutch national team if you’ve got nothing about you
“I think they’ve got a good man, but how long he’ll be there we’ll have to see because he doesn’t usually stay at clubs for long.
“You’ve got to make decisions and you can’t be afraid of making decisions. And they’ve got a man now who doesn’t give a toss about anything except the football club.
“The thing that lets him down at times is how he treats people in and around the club, but we’ll soon find out. It’s very important for them to get back in the Champions League and Van Gaal is the man who gives them the best chance of doing that.”
Manchester United currently sit in seventh in the Premier League following their 3-1 over Hull at Old Trafford last night.
