Celtic are interested in signing Sheffield United captain Billy Sharp, reports the Guardian.
The Blades bought in three new forwards in the summer ahead of their first Premier League season in 12 years.
That has limited the game time of Sharp, who has started just one league match in 2019/20. The striker has been used extensively from the bench, though, with a further 10 substitute appearances.
This lead to speculation Sharp could leave during the January transfer window and the reigning Scottish champions are apparently interested.
The Yorkshire Post claims that Championship leaders Leeds United are another side keeping tabs on the 33-year-old. Sharp previously played for Leeds during the 2014/15 campaign before rejoining the Blades.

Sharp is under contract at Bramall Lane until 2021, having only signed a new two-year deal in February.
When the skipper was last linked with an exit from the club, manager Chris Wilder was quick to shut down the speculation.
“You can read hundreds of thousands of reports about us being linked with players and players being linked with us,” said Wilder.
“He’s a talented player, who has done fantastically well. He doesn’t want to go anywhere, I don’t want him to go anywhere.
“So, as far as I’m concerned, that’s the end of the conversation with him.”
It would therefore be something of a surprise if Sharp were to leave for Celtic Park – or anywhere else – this month.
Although his time on the pitch has been more limited this term, the attacker is finally getting to test himself in the top flight. And with his boyhood club.
Sharp previously only managed 18 minutes of Premier League football during a brief spell with Southampton. Yet after rejoining the Blades four-and-a-half years ago, he has played a key role in their rise through the divisions under Wilder.
Over two spells with the Blades, Sharp has scored 103 goals in 254 games.
