Bayern Munich's executive board chairman Karl-Heinz Rummenigge is optimistic that Rafinha and Arjen Robben will agree new contracts at the Allianz Arena.
Robben's current deal with Bayern expires in 2015 and president Uli Hoeness confirmed last week that he is not worried about losing the Netherlands international.
Rummenigge also believes that the winger is happy with the European champions and will extend his deal with Bayern.
"I am optimistic that Arjen will stay at our club," Rummenigge told Sport-BILD weekly. "He loves Munich!"
Rafinha's contract expires at the end of the season, but Rummenigge feels the Brazilian full-back will stay after becoming a first choice under coach Pep Guardiola.
Rummenigge added: "Rafinha is a terrific fellow. He is on a contract until the end of the season and I have the impression he is keen to stay at our club."
Meanwhile, Bayern defender Jan Kirchhoff is not worried by his lack of impact at the club since his summer move from Mainz.
Kirchhoff has yet to start a game in the Bundesliga or UEFA Champions League this season, but the 23-year-old feels he will progress under Guardiola.
He told kicker-Sportmagazin: "I really knew this transfer would be a big step. Therefore, I definitely need time to settle at Bayern Munich, there is no doubt.
"You should not forget my last year at Mainz was pretty difficult and also that my pre-season was physically not the best.
"Of course, it's tough to always keep cool. But I am here to progress and become a real option. I know I have to improve a lot of things to be a really good option for the manager."
