Former Brazilian World Cup winner Pele could be coming out of retirement at the age of 70.
Pele's former club Santos are keen to register him for December's Club World Cup and talks between both parties have reportedly taken place.
Brazil's all-time leading goalscorer is believed to have started a training regime in case he decides to accept the offer from Santos.
"Pele was positive and promised to train to get fit and participate for a few minutes, if possible," Santos president Luis Alvaro de Oliveira Ribeiro told Radio Globo.
"I have talked to [coach] Muricy [Ramalho]. Now the only stumbling block is Pele. He would be registered with the number 10 shirt."
Pele twice won the Club World Cup as a player with Santos in 1962 and 1963.
