PSV Eindhoven has submitted an improved offer for U.S. youth international and Hannover 96 defender Chris Gloster, a source with knowledge of the situation told ESPN FC.
The source said that the improved bid was made on Friday, and follows a previous offer that was made at the end of June.
Hannover has told Gloster he will be part of the first team this season if he remains, and he was included in the club's first-team photo that was posted earlier this week.
But the prospect of playing in the Champions League or Europa League -- if not this season then in subsequent campaigns -- holds considerable appeal for Gloster.
