Sunderland have reportedly offered £10m and striker Fabio Borini for Swansea City and Ghana forward Andre Ayew.
According to Sky Sports sources, the Black Cats have been pursuing Ayew for several weeks and are understood to have made an initial approach for the player 10 days ago.
The Ghana international has been one of the better performers in an otherwise disappointing campaign for Swansea, scoring eight Premier League goals since his arrival from Ligue 1 outfit Olympique Marseille.
The Ghanaian scored a vital goal for Swansea in Sunday’s 2-1 win over Everton last weekend and new manager Francesco Guidolin is said to be reluctant to lose the 2015 African Footballer of the Year second runner-up.
For a player who came on a free in the summer, the offer from Sunderland could be tempting for the Swans.
