According to The Sun, Sunderland hope to fund a move for Fenerbahce forward Moussa Sow by selling Steven Fletcher to Celtic.
The Black Cats need attacking reinforcements this summer, and The Sun believe Fenerbahce's Senegalese international Sow is Dick Advocaat's top target.
The 29-year-old could cost up to £7.5m according to the report, and Sunderland need to raise funds in order to afford Sow this summer - and could look to sell Fletcher to do it.
Fletcher, 28, has scored just eight goals in the last two seasons, and with Sunderland looking for a greater return from their forwards, the Scottish international is primed for the chopping block.
The report from The Sun states that Sunderland will try to engineer a deal to send Fletcher to Celtic, and use the money to buy Sow in his place - but whether Celtic could afford him is another matter.
The Bhoys certainly need to bring in a new striker this summer, but assistant boss John Collins told the BBC that Celtic would not be able to afford Fletcher due to his wages.
Worth the money?
Fletcher would represent a clear upgrade over Stefan Scepovic and outgoing loanee John Guidetti, and he could be the man to make an impact for Celtic in the Champions League qualifiers this summer.
Fletcher's goals could help Celtic progress further into the competition, making his goals essentially pay for themselves in additional TV revenue that comes with playing in Europe's top club tournament.
It's a big risk for Celtic to take financially, but it's one they should consider, with Fletcher having the ability to make Celtic a dangerous force in Europe next season and beyond.
