Lampard confirmed Monday that he would be ending his 13-year stay at Chelsea after the Premier League club decided against offering him a new contract.
"The American thing is an option. I'm looking at different options but I want to carry on playing," Lampard, who will captain England in its friendly against Ecuador on Wednesday, told the media.
While the midfielder is eager to sort out his club future, the 103-cap veteran expects that a decision will not be made until after the World Cup in Brazil, where the Three Lions will come up against Italy, Uruguay and Costa Rica in Group D.
"I'd like to get it sorted soon — not in World Cup time but after that. I'm not sure it's possible to do now," he said. "I'm a big enough boy to get on and concentrate fully on this World Cup with England."
England kicks off its World Cup campaign against four-time champion Italy in Manaus on June 14.
