The 45-year-old actor, who plays Syed's father Masood Ahmed on the soap, told the BBC Asian Network that Syed will soon return to his old "dodgy" ways.
Syed, who was caught stealing money from the family business in his younger days, has appeared to settle down in the past couple of years, but Ganatra suggested that the character will soon have a new storyline where his 'flaws' comes to the fore again.
On what Syed will be up to in future episodes, Ganatra replied: "All of his shenanigans. I don't know if you remember, Syed when he first came on the show was into businesses, and was doing some dodgy dealings with money and stuff like that.
"I think it's a return to that kind of character, who is always up to something dodgy when it comes to money.
"I think it's good to return to the origins of a character, just to refresh it a little bit, and I think it's gone back to that. He wants to make a name for himself financially, but Syed's character is flawed like the best characters are. He messes it up again."
EastEnders viewers have recently seen Syed forced to close down his latest business, while it has been rumoured that newcomer Danny Pennant (Gary Lucy) will be involved in a love triangle with Syed and Christian Clarke (John Partridge) when he arrives in Walford.
