Dann is about to make a return from injury to find that both the clubs that showed an interest last summer are sniffing around again.
Arsenal boss Arsene Wenger let the chance to sign him go in the summer as he had reservations about his fitness and injuries, but he is now thought to have renewed interest.
At Aston Villa they have Alex McLeish in charge and he has already worked with Dann at Birmingham City and remains a big admirer.
