The former Chelsea striker impressed in his maiden appearance for the Chinese club, coming off the bench at the break before providing the crucial pass for the equaliser
The Argentine had said that Drogba would likely only make a brief cameo appearance off the bench against R&F having arrived in China last week short of full fitness.
However, the Ivorian came off the bench with his side trailing 1-0 at the break and produced an encouraging display, including an incisive left-footed through ball which set up Cao Yunding for a 68th-minute leveller.
Drogba also tested R&F keeper Cheng Yuelei shortly after coming off the bench with a wicked 35-yard free-kick, while he headed over from Feng Renliang's cross moments later.
"I said before the match that Drogba could play 30 minutes according to his physical condition, but I was wrong. He showed his uniqueness in the team, although he has yet to do more to recover," Batista told reporters after the game.
"I had to talk with Didier in the dressing room [at half time] and he felt he could deal with the 45 minutes left. So we decided to let him play, you could say it is in time. He needs more time to get fit, but he is an important member of our team."
He added: "He felt very happy after the game, he felt he was fit and very comfortable to play alongside [Nicolas] Anelka and [Giovanni] Moreno."
Batista also hinted he may elect to use Drogba up front with Anelka in an attacking-midfield role in the future.
