"Don't get me wrong, I've had a fantastic time at Crawley, we've been going very well in the league, the people are great there," he added.
"Of course I'll be excited to be back in the Bournemouth colours, but I'll feel a lot better if I can start with a win on Saturday.
"We've got to believe we can get out of the situation, and the nitty-gritty starts now. We've got to fight for every point."
Fletcher is Bournemouth's record appearance-maker - having made over 580 appearances in his first spell with the Cherries after joining from Hartlepool in 1992, while scoring over 100 goals and having a long stint as club captain.
He was on target when they won the Third Division play-off final by beating Lincoln City 5-2 in 2003, and was voted as the club's all-time cult hero by viewers of the BBC's Football Focus two years later.
After being released by former Cherries boss Kevin Bond in 2007, he made 39 appearances for Chesterfield in 2007/08 before looking for a club nearer his south coast home - and joining Crawley.
He scored two goals in four league starts and 17 substitute appearances for the Red Devils - but now faces a battle to keep the Cherries in the Football League, as they are 10 points from safety with 21 games remaining.
