Southampton owner Markus Liebherr has died at the age of 62.
The cause of the German-born businessman's death was not disclosed in a lengthy statement released by the club.
It read: "Anyone who came to know Markus learned of his quick wit, love of football - most especially Saints football - and his unquenchable thirst for better knowledge of all things."
It continued: "Anyone who had the privilege of meeting Markus met a man who was quiet, unassuming, undemonstrative and fantastic fun to be with.
"To say he will be missed is an unmistakable understatement."
The Saints statement went on to promise that Liebherr's dream of a Premier League return for the club would be achieved.
"What would Markus want now is a question that will be on everyone's lips," it read. "He would have wanted to be there when the Saints get promotion to the Premier League.
"The well laid plans for the club that he and the executive chairman had mapped out over a year ago will continue to be implemented uninterrupted and nothing will change in that regard.
"The club will ensure that Markus' wishes are carried out in full."
A book of condolence is to be made available to fans, while there will also be a memorial service in his honour.
