Chelsea winger Callum Hudson-Odoi is close to a loan move as he seeks more game time.
But other offers are being considered by Hudson-Odoi, who made 15 Premier League appearances last season and has not featured in this campaign.
It is understood Chelsea would allow a loan deal, but do not want to lose the 21-year-old permanently.
Having being left out of the squad for Chelsea's opening Premier League game at Everton and an unused sub against Tottenham on Sunday, Hudson-Odoi's departure would be the latest sign of manager Thomas Tuchel reshaping his attack.
Christian Pulisic has also been linked with a loan move to Manchester United, but it is understood Chelsea would not be willing to sanction a deal to a traditional rival.
