Douglas Costa could hold talks with Bayern Munich this summer about a transfer.
"It's obvious that both parties need to be happy in a contract," agent Junior Mendoza told Sport Bild.
Mendoza is reportedly surveying the market for a potential transfer.
Tottenham Hotspur could be a potential spot for Costa, though Jiangsu Suning have also shown interest.
After joining from Shakhtar for €30 million in the summer of 2015, Costa enjoyed a solid first season in Germany.
Costa contends for a place on the flanks with Arjen Robben, Franck Ribery and Kingsley Coman.
