Celtic are 'open to offers' for lifetime servant James Forrest, it has been claimed.

talkSPORT reporter Alex Crook states that it's set to be a busy day at Parkhead in terms of outgoings.

David Turnbull is set to complete his £2m move to Championship side Cardiff, while West Brom are closing in on Mikey Johnston.

However, the shock update regarding the Hoops is that Forrest - the club's longest-serving player - could well be away.

Crook tweeted: "Busy day of exits at #Celtic with David Turnbull set to join #CardiffCity and Mikey Johnston moving to #WBA on loan.

"Also told they are open to offers for long-serving James Forrest."

Forrest, 34, has struggled for game time since Brendan Rodgers returned as manager in the summer. 

He's featured just 18 times this campaign, mainly from the bench in cameo appearances. 

Forrest's current Celtic contract is due to expire in the summer of 2025. The Scotland international has won 22 major trophies at Celtic.

Meanwhile, Alan Brazil has made an astonishing claim regarding Brendan Rodgers' happiness at Celtic.

The Hoops-daft radio host this morning stated that he's heard 'rumours' about the Irishman's frustrations in the job at Parkhead.

The talkSPORT presenter admits he's worried that Rangers could reel the champions in as the title race heats up in the Premiership.

However, his co-host Gabriel Agbonlahor did try to cool his concerns after asking when was the last time the Ibrox side managed to inflict defeat on Celtic.

Of course, that came in the post-split fixtures last season. Michael Beale's men beat Ange Postecoglou's side 3-0 at Ibrox.

Just five points separates the teams at the summit of the table, with Rangers holding a game in hand over their arch-Glasgow rivals.
