Humphreys, 20, has been on the books at Chelsea since 2017 and he has already witnessed a loan spell at Paderborn.
The talented defender has attracted interest from Swansea, with Michael Duff’s side keen on further additions to their defensive ranks.
The Swans have held talks with the Blues about a loan deal for the England Under-20s star and the Championship outfit were hopeful they would be able to sign him.
However, Chelsea have yet to sanction an exit for Humphreys amid claims they could even keep hold of him and that has left Swansea playing the waiting game.
The Welsh side could consider looking at other options if they feel they will be waiting too long for Humphreys.
Swansea are eager to improve their defensive performances this season amid their hopes of securing a playoff spot.
Humphreys is a highly rated and has also been linked with Swansea’s Championship rivals Stoke City.
