The former FCB star believes that the current Bundesliga leaders already have plenty of quality and do not need to make any big investments
The Bayern icon stated earlier this week that he would love to see Rooney at the club, but he has now stressed that he does not think the Bundesliga giants need any more stars.
"The team is strong enough. If Guardiola manages to improve a few of the players we already have, he doesn't really need any new signings," Beckenbauer told Bild.
"What's the point of making big investments to sign more stars... That will only prompt opponents to play even more defensive.
"We will not sign someone like [Lionel] Messi. Neymar would be quite something, but he will not move until the World Cup.
"And he will be way too expensive after that. They are now already talking about a €70-80 million transfer fee."
Neymar has also been linked with clubs such as Barcelona and Real Madrid, with the Catalans supposedly sitting in pole position to sign the Santos star.
