The striker has rejoined the club on loan from Southampton and is looking forward to getting his third spell at the Keepmoat Stadium underway.
"I just want to play football and hopefully score a lot of goals again to help the team out and get them climbing the table," Sharp told the media on Thursday.
"I had a great spell here last time and hopefully I can do it again - and do better than I did last time.
"I've got a great relationship with the fans here and I had my heart set on coming here and I made sure I made it happen from my side.
"The gaffer (Paul Dickov) has worked hard along with the team and the board and I'm just delighted to be on board again.
"This was the right move for me at the right time. It's my third loan spell in two seasons which doesn't help but I just felt this was right and hopefully I can be successful."
Sharp first joined Doncaster during the 2009/10 season on loan from his boyhood club Sheffield United.
He scored 15 goals in 34 appearances for Rovers, prompting them to sign him that summer for a club-record fee of B£1.1million.
The striker continued his form in front of goal, netting 26 times in 47 starts before moving to Southampton for B£1.8million in January 2012.
Despite aiding their promotion to the Premier League, Sharp has never been given a chance by Saints in the top flight and spent last season on loan at Nottingham Forest, where he scored 11 goals.
During the first half of this season, the 27-year-old was farmed out on loan to Reading and scored twice for the Royals.
