Raheem Sterling's representatives want "clarity" about the forward's future at Chelsea after he was left out of the squad for Sunday's Premier League opener against Manchester City.
In a statement his representatives said Sterling has a "good working relationship" with new Blues manager Enzo Maresca but there was an "expectation" he would be involved in Sunday's match at Stamford Bridge.
Chelsea have spent about £185m on 11 signings this summer, leaving Maresca with a squad of more than 40 senior players.
"He returned to England two weeks early to conduct individual training, and has had a positive pre-season under the new coach, who he has developed a good working relationship with," said the statement.
