David Templeton has denied claims by Hearts he "switched off completely" this year and had been determined to secure a move away from the club.
Templeton, who scored two goals on his Rangers debut on Sunday, was criticised in a statement by Hearts after he signed for the Gers on Friday.
Hearts accused the player of a lack of focus and said former manager Paulo Sergio had "issues" with the player's attitude, resulting in his omission from the Scottish Cup final squad.
"They are only doing it to cover themselves and I'm just looking forward to being here," Templeton said.
"I was there for five-and-a-half years and I gave everything no matter what and I'll do that whatever club I play for."
He added: "I don't see joining Rangers as a lack of ambition. It shows my ambition as I want to help Rangers get back to where they belong."
Rangers boss Ally McCoist added: "I don't want to get involved - but every player who has left this club has gone with our best wishes.
"Maybe that's the way to do it but I don't want to get involved in a slagging match. I don't claim to know David well but I don't see him having an attitude problem."
