The former Albiceleste coach quit his job at Mexican second division outfit Dorados in June for health reasons after just nine months in charge.
Earlier Thursday, Pellegrino had met with Morla in Puerto Madero to finalise the contract, before heading off to meet the footballing legend at his home in the town of Bella Vista, Buenos Aires Province.
Argentina's 1986 World Cup winning captain has been recuperating in Buenos Aires over the last few months after undergoing a knee operation in July. He said earlier this week that he was ready to return to football.
Speaking in a video posted on Wednesday, Maradona thanked Gimnasia for their interest in hiring him and said he was recuperating nicely after undergoing surgery on his knee. According to press reports, he may also have to undergo surgey on his left shoulder, which was last operated on in 2017.
"I have been operated on very recently. That the people of Gimnasia... have put me again [under consideration) for my distant achievements or because they are 'Maradonian' – it is a very nice thing," said the former Albiceleste star and coach.
Prior to his tweet, Morla had publicly expressed confidence that a deal would be signed. “The agreement is 80 percent done, all that remains is to agree formal and administrative data – that will be resolved," he told TyC Sports.
"Currently, we have 25,000 associates of which just under 20,000 pay. Today, before the headquarters opened, there were fans queuing to join up," he said.
"We also hope for the arrival of new sponsors, to cover the free spaces on the shirt and to see if we can negotiate television rights for training sessions, in addition to some other lower income," Marzola told the Noticias Argentinas news agency.
"Honestly, I had no dimension of everything that arrives, that Maradona could generate. People are crazy, the phone does not stop ringing – friends from Boca, River, Estudiantes are calling and we even had foreign media [getting in touch] to cover the presentation. We expect a lot of revenue if Diego comes," he said.
