Celtic-daft Alan Brazil has started the pre-match derby verbals early - by calling out Ally McCoisrt live on the talkSPORT airwaves this morning.

The radio host insists the Rangers hero isn't confident about his team heading into tomorrow's powderkeg clash at Celtic Park.

And despite McCoist rarely appearing on the station on a Friday morning, Brazil couldn't resist a cheeky pop at his usual sparring partner.

He said: "Has anyone seen McCoist? Please let us know.

"He rejected all our producers calls yesterday. He's clearly just not confident."

Rangers make the short journey across Glasgow tomorrow knowing that anything but a win realistically sees Celtic win the Premiership title.

Brendan Rodgers' side is three points clear at the top of the table, and boast a superior goal difference.

Each team still has two games remaining after the derby encounter in Glasgow's east end, with Celtic set to travel to Kilmarnock and then host St Mirren, while Rangers will play Dundee and visit Tynecastle.

Glasgow's big two will do battle for the last time this season in the Scottish Cup final on Saturday, May 25 at Hampden Park.

Meanwhile, the four nominees for the Scottish Football Writers' Player of the Year have been announced.

Lawrence Shankland has already claimed the PFA Scotland award, and the Hearts talisman is once again up for this one. 

He is joined on the SFWA list by Rangers' Jack Butland, Celtic's Matt O'Riley and Aberdeen frontman Bojan Miovski.

The latter - who has 24 goals in all competitions for the Dons this campaign - replaces James Tavernier from the PFA nominees.

Shankland has 28 goals this term, while Jack Butland is credited with keeping Rangers in the title race with pivotal saves in big games.

Matt O'Riley has enjoyed his best season to date at Celtic Park under Brendan Rodgers, and his form could well lead to a mega-money move abroad this summer.

If either Shankland or Miovski wins the award, they will become the first non-Old Firm player to pick it up in 11 years.
