Wellens re-signed for his former club on the eve of the new season, putting pen to paper on a short-term contract when a longer deal was in thepipeline had this summer's much-publicised takeover at the Keepmoat Stadium materialised.
With those investment talks on hold, the current agreement suits both parties. Dickov has added another much-needed body to his small squad, while Wellens effectively gets a shop window to showcase his ability should prolonging his stay in South Yorkshire prove to be out of the question.
Other clubs are known to be monitoring the 33-year-old's situation but Dickov remains optimistic about holding on to the player.
"I wouldn't be playing him if I didn't think we had a chance of keeping him," Dickov said.
"His contract is as long as a piece of string but I am confident we can keep him."
Wellens, who made almost 100 appearances for Doncaster between 2007 and 2009 and helped them win promotion to the Championship, began training with Rovers towards the end of July after having his contract with Leicester cancelled by mutual consent.
After signing his short-term deal on August 2, Wellens started for Dickov's side the following day as they got their Sky Bet Championship campaign under way at home to another of his former clubs, Blackpool.
The former Manchester United trainee also started Tuesday night's Capital One Cup win over Rochdale.
