McAvennie delivers two-word pained verdict after Rangers-Celtic news emerges today

Frank McAvennie claims the first Old Firm of next season will be a good gauge for Celtic to see if they can challenge Rangers. 

The Hoops icon, speaking exclusively to Football Insider, was reacting to Tuesday’s SPFL fixture announcement.

It was announced on Tuesday that Celtic will travel to Ibrox on the fourth weekend of the 2021/22 season.

Celtic failed to beat Rangers in five attempts last season, losing four and drawing one Old Firm clash.

Last week, Celtic confirmed the appointment of Ange Postecoglou, who now has to prepare for one of the biggest games in world football early in his Parkhead career.

McAvennie insists Celtic’s only mission should be to go to Ibrox and win though he admits that is unlikely.

“Oh god, it doesn’t get tougher than that,” McAvennie told Football Insider correspondent Ben Wild.

“Hopefully Rangers are still celebrating winning the league and aren’t up to it. 

“It’s always going to be tough whether it’s the first game or the fourth game. You have to go there and beat them. There’s one mission, beat them.

“It’s as simple as that. So no pressure Postecoglou, all the best with that Ange. It will be a gauge of where they are. 

“He should have his own players by then and it will be easy to see how good they are when they face Rangers.”

The Hoops finished 25 points behind Rangers last season.

The Gers went unbeaten as they won their 55th league title.
