Speaking to media representatives at the Oktoberfest, Hainer said the day was for enjoying the festival rather than talking about deals.
“Today is a day to enjoy the Oktoberfest. We will talk about contracts later. But I am very confident. He feels extremely comfortable in Munich, as does his family – he can win titles with us.
"He has never won so many titles as since his move to Bayern. He knows how to assess that, and we know it too.”
Kane, 33, is only under contract with Bayern Munich until the end of the season. Talks about an extension have been going on for some time, and both sides basically want to continue working together, according to Fussballtransfers.
But it is not a foregone conclusion, and the parties have not yet agreed on the length of the deal or the exit clause. Indeed, Kane expressed interest in trying another league last week before he hangs up the boots.
