According to the Daily Mail, Celtic are hoping to sign Sunderland striker Steven Fletcher before Tuesday's transfer deadline.
The Bhoys have added one striker already this summer in Nadir Ciftci, but the Daily Mail believe that two Celtic forwards - Anthony Stokes and Stefan Scepovic - are ready to leave the club within the next 24 hours or so.
That would leave manager Ronny Deila with a hole to fill up front, and Scotland international Fletcher appears to be the top target.
The 28-year-old hit just eight goals in his last two seasons for the Black Cats, and now appears to be slipping out of favour under Dick Advocaat, with the Black Cats looking to bring in another striker before the deadline.
Fletcher will need to play regularly to keep his place in the Scotland side, and the Daily Mail believe that Celtic are ready to offer him a return to Scotland.
It's reported that, with Celtic concerned over Fletcher's high wages, Sunderland are prepared to pay a chunk of the striker's wages in order to facilitate a move to Glasgow.
The deal would be an initial season-long loan deal at Celtic Park, with a view to a permanent move next summer if Fletcher impresses - which would certainly be an ambitious move from the Bhoys.
Fletcher may have struggled with Sunderland of late, but he certainly has the quality to be a star in the Scottish Premiership once again, for the first time since leaving Hibernian for Burnley back in 2009.
The Bhoys may need to sell defender Virgil van Dijk to fund such a move, but Fletcher could also make an impact in the Europa League too, giving Celtic a boost in the final third.
