Naldo has urged new Schalke teammate Leroy Sane to stay where he is.
Sane is a top target for Manchester United and Manchester City this summer.
ESPN says Naldo who will join Schalke on a free transfer from Wolfsburg and has urged the winger to remain at Schalke for another season to further improve.
The 33-year-old says that Sane should follow the example of his former Werder Bremen teammate Mesut Ozil, who rejected high-profile offers in 2009.
Ozil became Werder's main playmaker -- making 46 appearances and securing his place in the national team for the 2010 World Cup.
