Poyet is the manager of Chinese Super League club Shanghai Shenhua and is interested in Chelsea captain Terry.
The defender is set to leave Stamford Bridge at the end of the season and is keen to carry on playing.
A new rule was announced in January that Chinese Super League clubs can only play three non-Chinese players per game.
And former Chelsea and Tottenham midfielder Poyet says the change means a deal for Terry is much more unlikely than it could have been but he isn’t giving up hope.
“I think the situation with John, if you asked maybe in December before they changed the rules, I would say straight away he was coming, 100 per cent sure,” he said on talkSPORT.
“I would have no doubt. Now with the new system it is a little more special to sign a defender.
“We changed a lot our mentality now because we are always looking for the players that will make the difference up front, the ones that will bring people to the stadiums.
“We are like that.
“It would be a possibility for sure.”
