Reports claimed the right-back had been sacked by Augsburg after he "violated" the club's code of conduct and "repeatedly lied".
Opare is said to have held talks over a deadline day transfer to Schalke 04, although no such move materialised.
According to the Sun, Leicester and Stoke had been alerted to the Ghanaian's availability, after Augsburg said he could find a new club.
But Chris Nathaniel, who represents Opare on behalf of NVA Sports and Entertainment Group, has insisted via the newspaper that his client remains on Augsburg's books.
"I am shocked by the recent false and malicious statements about my client Daniel Opare," said Nathaniel, as quoted by the Sun. "Firstly, he is still contracted to FC Augsburg and will be there until the end of the season when his contract ends so the talk of him being sacked are incorrect.
"I received a call from FC Augsburg on Thursday stating unless my client signed the contract they had offered in two days he would not play for the club again.
"The offer from the club did not meet my clients requirements and he was subsequently banished from first-team activities and even asked to clear his locker, which I found petty and unprofessional considering he has been at the club for some 30 months.
"The malicious comments made by [Augsburg's general manager] Stefan Reuter highlights how bitter the club are due to him not signing their contract.
"Daniel will continue train hard and will be available to help the club if called upon and it is ironic his temperament was never put into question before the contract issue.
"Finally Daniel has five months on his contract so he is entitled legally to talk with any club. He is proud to be linked with clubs like Leicester and Schalke but he has been and will continue to be focused on helping Augsburg finish as high in the league as possible whenever called upon."
Summer move still on?
Despite Nathaniel's comments, Opare might not be an Augsburg player for much longer anyway, with his contract due to expire in June.
Whether Leicester or Stoke - who signed right-back Moritz Bauer last month - will still want him by then, however, remains to be seen.
Even if Opare is released now, FIFA rules would prevent him from signing for a new club until the summer, as he was seemingly still under contract when the deadline passed.
Wolverhampton Wanderers and Everton were also linked with moves for the 27-year-old during the January transfer window.
Should Leicester City / Stoke City move for Opare this summer?
