Celtic are reportedly back in the hunt to sign Brondby striker Mathias Kvistgaarden.

The Parkhead club were previously linked with a move for the 21-year-old in the summer.

No transfer exit from the Danish club was sealed in the summer, but it's now claimed clubs are circling round Kvistgaarden ahead of the January window.

A report in Tipsbladet claims Celtic are among the clubs interested in Kvistgaarden as well as Bundesliga clubs and some Premier League and Championship sides tracking the striker.

The report states: "I know from good sources in Scotland that Celtic are back on the pitch.

"They sit in the domestic league, but Brendan Rodgers, who has returned as head coach after his time at Leicester, wants more power for the offensive, and you have ambitions to do more than get the scratches you are currently getting in the Champions League."

However, Kvistgaarden would require a significant transfer fee to take the striker from Brondby.

It's reported Brondby value the striker at 75million Kroner, or in the region of £8.5m.

The report states Brondby would be unwilling to allow the forward to leave on the cheap with a fee already set out for any potential deal.

The Tipsbladet article continues: "I fully understand that Brøndby has no intention of letting Kvistgaarden go cheap: They will then go after their 75 million kroner, 10 million euros, a nice round number, in the work to get higher in the sales hierarchy in the top of the Superliga.

"It is expensive for a player in January, but in the right club, Kvistgaarden will also be a gain with his ongoing style."
