Sunderland and Swansea City are chasing Celtic defender Virgil van Dijk.
Voetbal International says the two Premier League clubs are in talks with Celtic about tempting the Dutchman south.
Van Dijk is tied to Celtic until 2017, but is tempted by a move south.
The centre-half is likely to be on the move after Celtic were thumped by Champions League opponents Legia Warsaw last night.
Both Swansea and Sunderland are in the market for a new centre-half signing this summer.
