Sevilla chief Monchi hasn't given up on bringing Marko Marin back to Spain.
The Chelsea midfielder helped Sevilla win the Europa League last season and remains available after failing to find a new club this summer.
Eintracht Frankfurt and Hannover have been linked with Marin in recent weeks, though nothing concrete has materialised.
Monchi is now back in talks with Chelsea about a new deal for the midfielder, but lacks the spending power to consider an outright transfer.
For his part, Marin would welcome a return to Sevilla, where he established a close relationship with local fans.
