Former Chelsea manager Gianluca Vialli believes Frank Lampard should leave the club at the end of the season.
Lampard is out of contract in the summer but is expected to consider a new deal if Jose Mourinho returns to Stamford Bridge as manager.
However, Vialli, who won five trophies whilst in charge of Chelsea, believes the time is right for Lampard and the Blues to part ways.
He told Sky Sports News: "In my opinion it's probably the right time for them to say goodbye to each other and leave on good terms.
"Frank has a fantastic opportunity to try something new, perhaps in Los Angeles or somewhere else in America, have fun for the next three or four years and make some money.
"Then one day he could perhaps come back to Chelsea as a hero. I really hope he scores a few more goals to become their top-scorer in the history of the club."
Vialli expects Mourinho to return to Chelsea this summer and believes it would be a good appointment by the club.
"I don't know whether it's a done deal but I expect Jose to be in charge next season," he said.
"I think he is a good choice. He is unbelievably motivated; he's got a passion for English football and for Chelsea. He is a winner."
The Magpies have failed to back-up last season's top-five finish and are in the midst of a relegation battle heading into Sunday's game at QPR.
With an eight-year contract to his name Pardew would not be expected to be made to pay for results, but the former West Ham manager knows that could end up being the case.
"Mike and I will sit down as soon as we know what division we're in," he told a number of national newspapers.
"We know we've got an uncomfortable conversation regarding the form this year, the under-achievement and everything else.
"We need to find out what the reasons were and then it's for Mike, and hopefully with me, to decide how to go forward. It's a privilege and honour to be manager of this club.
"But Mike could decide he needs a new manager. I like to think that he won't, that next year he'll stay with myself."
Pardew's men are one place outside the drop zone with two games left. A victory on Sunday would leave them vulnerable only to Wigan winning their last two games and other results going against them.
