The Bayern Munich duo both entered the final years of their respective deals with the Bavarians and have been linked with a move away from the club as the negotiations over a contract renewal seem to be stalled.
Kimmich has just entered the final two years of his current contract at Allianz Arena, while Goretzka only has 11 months left on his Bayern contract while he’sheavily linked with a move to Real Madrid or Manchester United
"They will certainly not be kept at any cost," the Allianz Arena chief, Hainer, toldKicker
: "The players know what they have at Bayern, they are paid very well here too, everyone gets their salary.
"And they can win titles with us now, and also in the future."
On UEFA’s planned 'luxury tax', which is set to be introduced to punish any clubs that exceed the new agreed wage cap in Europe's major leagues, Hainer said: "I'm not at all convinced by this luxury tax. In the event of violations, a club pays 100 million euros in luxury tax, which is shared among the other clubs.
"This money does not help them decisively and does not really hurt the financial giants. We need valid regulations with clear consequences for fair competition.
"Strong attempts at sanctions have too often been revised or toned down in the past. It doesn't work that way."
"We are monitoring the transfer market, which is open until the end of August, to see whether there are still one or two possibilities," he added. "But we almost exclusively have national team players of the highest quality, so there is no urgent need to sign someone quickly."
