Disagreements over money caused talks between Dovizioso and Ducati to come to a standstill last month, in which time current Pramac rider Jack Miller was named as the factory squad's first confirmed rider for next year.

Battistella also moved to dismiss speculation that Dovizioso could be mulling retirement.
"There are those who question his motivation, but he's super-motivated, he's trained a lot every day, he's in the best shape since I've known him," he said of the 34-year-old.
Dovizioso's only other realistic avenue to stay in MotoGP, KTM, was officially closed off earlier this week with the news that the Italian's current teammate Danilo Petrucci will be joining the satellite Tech 3 team for the 2021 season.
Battistella clarified that Dovizioso had been approached about a potential move to KTM but that talks did not progress very far.
"We even met, but it was a negotiation that was over quickly, because they could not meet our prerequisites," he said of the Austrian manufacturer.
