Frank Lampard is looking ‘very carefully’ at the situation with Chelsea’s out-of-contract stars.
Olivier Giroud, Pedro, Willian and Willy Caballero will be able to leave Stamford Bridge when their deals expire on June 30.
However, the 2019/20 campaign looks set to run beyond that date due to the coronavirus pandemic, which has suspended top-flight football since March 13.
New rules allow clubs to agree short-term extensions with their out-of-contract players in order to complete the current season.
Chelsea boss Lampard told the club’s official website: “We have big players in that position so that’s obviously something I’m looking at very carefully.
“The ones out of contract here have been great servants for the club and actually have a lot of feeling for the club.
“But of course they will be concerned about themselves in terms of how they are now, and if pre-season is rushed they’ll want to make sure they’re alright.
“So it’s going to have to be something we look at. Hopefully we can have that arrangement so they can stay with us because if we play again I would love the squad to look as it’s looked all season, but we’ll have to see how that works.”
Pedro has been used sparingly by Lampard this season, but Giroud, Willian and Caballero were featuring regularly before coronavirus hit the UK.
The Premier League’s ‘Project Restart’ proposal aims to resume top-flight football on June 12.
Lampard wants to make his Chelsea players feel comfortable with most of them set to return to training this week.
He added: “It’s been a job for us as staff to plan how phase one will look because it will be quite different due to the restrictions on how we can work.
“It’s good for the players because they will be wanting to get back training in the right conditions; we know it’s difficult circumstances for everyone so it’s going to be a challenge to make sure that we get it right.
“Our job from the coaching side is to make sure we’re careful with the players. The first steps will have to be very careful but all managers will be thinking a similar thing.
“You can’t just tell them we’re going in this direction because this is something that’s affected everyone and their families.
“Football has been put in its place. Everyone wants to get back playing, we all miss it, but we need to know the players are comfortable.”
