Former Bayern Munich defender Willy Sagnol has questioned their move for Manchester City attacker Leroy Sane.
Sane is a confirmed summer target for Bayern.
But Sagnol told RMC: "He doesn't fit Bavaria at all in terms of character.
"He's a very unsteady player who always does his own thing. For me he is not made for this club.
"He has a lot of problems, at Manchester City and in the national team.
"It is said that he costs 80 million euros. When in doubt, I prefer to invest 20 million more and buy Havertz."
