Sharp has been linked with a move away from St Mary's this summer after spending the majority of last season on loan at Nottingham Forest and he has not been involved in Southampton's pre-season trips to Austria and Spain.
Celtic, Barnsley, Sheffield Wednesday and former club Doncaster Rovers have all been linked with a bid to sign the 27-year-old, who joined Southampton in January 2012.
Quotes from someone purporting to be Sharp's agent claimed that the forward may have to consider his options if he is not going to be playing regularly under Mauricio Pochettino.
However, Sharp has confirmed that person is not his agent and he remains determined to make an impact in the Premier League at Southampton.
"I am not sure where these reports over my future came from as it wasn't even my agent," Sharp told Sky Sports. "My agent is Paul Masterton of First Eleven Sports and he deals with all my affairs.
"I am a Southampton player and I still have two years on my contract. I am happy to stay and fight for my place until I am told otherwise.
"It has always been a dream of mine to play in the Premier League and I will continue to make myself available to the manager.
"I have been linked with numerous clubs this summer but it is all just speculation as far as I am concerned.
"Until something more concrete happens I will then have a decision to make on my future but as it stands now I am a Southampton player."
