Borussia Dortmund would be happy to continue working with Jurgen Klopp beyond the expiry of his new contract in 2016.
The Signal-Iduna Park boss last month signed a fresh deal with the defending champions to replace his previous terms, which had been due to expire in two years.
But Dortmund chief executive Hans-Joachim Watzke has even offered Klopp a job guarantee beyond 2016 and cannot imagine ever wanting to say goodbye to the 44-year-old.
He told Bild: "I do not exclude much in life, but I can rule out that I would say in 2016 to Jurgen Klopp, 'We must part'.
"We are absolutely convinced with Jurgen. I've known him for four years, know how he works and have total confidence in him.
"We gave Jurgen a long contract, because we know he will get us through any hard times."
Dortmund captain Sebastian Kehl could be the next person to sign a new contract at the club after last week revealing talks have been taking place.
But midfielder Jakub Blaszczykowski may be leaving Dortmund and would prefer to move back to his native Poland.
