The 26-year-old has revealed he will finish the campaign at the npower Championship club as there is no clause in the loan agreement for Southampton to recall him in January. Beyond that, Sharp insists he would consider a permanent deal with Forest but at the moment he is only focusing on continuing to score goals for the club - with 20 his target for the season.
"When I signed for the season, I wanted some stability. So I didn't want there to be a clause where I could be recalled in January," Sharp told the Nottingham Post.
"The owners have said they do want to buy me. But a lot has to happen, they have to ask Southampton first for a start. There has not been a concrete offer but there has been talks between the main men and myself.
"But I am enjoying what I am doing, I am doing well - so I don't like to change things. I am here for the season at the very least because they cannot recall me in January. I didn't want that clause to be in the deal. I didn't want any interruptions.
"I will score as many as I can for Forest and then weigh my options up - and signing for Forest is a really good option. Something might still happen in January."
Sharp, who joined on a season-long deal at the end of August, has enjoyed a fruitful spell at the City Ground with nine goals in all competitions.
His latest came in new manager Alex McLeish's first game in charge against Crystal Palace at the weekend when his injury-time equaliser salvaged a 2-2 home draw.
Sharp added: "I have had a few injury problems in the last few seasons and I have not been able to get to that 20-goal mark. That has really frustrated me. Hopefully I can stay fit and get those 20 goals for Forest."
