Kris Boyd expects Danny Rohl to spring a formation change as Rangers take on Celtic in the Scottish Premiership at Ibrox.
Andreas Skov Olsen has been starting in recent games since his January move, but Boyd believes he could be dropped for this game.
In his view, starting Mohamed Diomande will give Rohl’s side a better chance of winning the Old Firm derby.

Kris Boyd believes Mohamed Diomande can thrive against Celtic
The former Rangers forward believes that there is only one place up for grabs in the current eleven ahead of the game against Celtic.
In his view, the 4-2-2-2 system that Rohl has deployed may not be the best option on Sunday.
He sees Rohl reverting to a three-man midfield, potentially a 4-3-1-2, with Mikey Moore in the hole, and Youssef Chermiti and Ryan Naderi leading the line.
Boyd backs Diomande’s previous performances against Celtic and believes he has what it takes to handle the pressure of such a big occasion.

Speaking to the Scottish Sun, Boyd said: “One place up for grabs and Diomande is the man for this occasion.
“The Ivory Coast midfielder has been good in recent Old Firm games and his half-time introduction turned the match at Parkhead in January.
“Diomande has scored a couple of goals against Celtic and his energy and bite could be crucial.
“It would be a tough call to leave out Skov Olsen, but Diomande can help Rangers get a grip of that midfield area.
“For me, putting Diomande in to help Raskin and Chukwuani would give Rangers a lot of power and drive.”

Rangers team news vs Celtic
Rohl will be without Connor Barron and Derek Cornelius for the Old Firm, as the duo have been long-term injury absentees.
Dujon Sterling missed training this week, but the German did not completely rule him out of action.
In the pre-match press conference, Rohl confirmed that both Sterling and Ryan Naderi were doubtful for this one.
If Naderi has not been declared fit, there is a possibility that both Skov Olsen and Diomande play in a 4-3-3 system.
