Lothar Matthaus believes Bayern Munich should target Timo Werner rather than Leroy Sane to reduce "the risk of agitation and bling-bling".
Former Bayern and Germany captain Matthaus has also predicted Manuel Neuer will move on at the end of the season, ending a nine-year stay at the club.
Head coach Hansi Flick, who has agreed a three-year deal after a successful spell in interim control, is expected to stamp his mark on the Bayern squad this summer.
That is likely to see a new forward joining, and Matthaus would prefer to see RB Leipzig frontman Werner arrive rather than long-time target Sane.
"My soft spot for Timo Werner is well known," Matthaus wrote in a column for sport.sky.de.
"And I don't mean to say that I don't think Leroy Sane is great. But you get the feeling that Flick and [Bayern board member Oliver] Kahn are more likely to see Timo Werner as the player who could be better suited to this club in many respects.
"He is more flexible on the pitch, his character may correspond a little bit more to the wishes of those in charge."
The comments from Matthaus alluding to Sane's character may cause some upset.
"The risk of agitation and bling-bling is significantly lower," Matthaus said. "He [Werner] can play at the very front in [Robert] Lewandowski's place, hanging behind or play on the wings. And he should also be cheaper."
Matthaus said Werner has "clearly developed this season, while pointing to Sane's lack of action at Manchester City due to a knee injury.
"I don't want to be misunderstood," Matthaus added. "Both players would bring added value to Bayern. But if I had to choose today, I would go for Timo Werner if I was in Bayern's place."
Matthaus sees Neuer, meanwhile, as approaching the end of the road at Sabener Strasse.
Bayern have signed Schalke goalkeeper Alexander Nubel, in a deal that will take effect at the end of the season, yet 34-year-old Neuer is reportedly seeking a long-term contract.
Matthaus suggested Neuer, whose current deal expires next year, should accept a three-year contract rather than push for greater security, but he has a hunch the long-standing number one will move on.
"I think the signs point to goodbye," Matthaus said.
"He wants to play. He wants to play more and longer. This is totally understandable with his quality. I don't think he will play in Munich again next season."
