Perry Groves suggests Old Firm clash could hinge on how two Rangers players are deployed

Rangers and Celtic meet in the Scottish Cup semi-final on Sunday.

Former Arsenal winger Perry Groves has suggested to TalkSPORT that Sunday's Old Firm clash between Rangers and Celtic could hinge on how Mark Warburton deploys two of his players.

Rangers go into the game as underdogs, due to their lower league standing, but with promotion already sealed the fixture will highlight the amount of work that needs to be done - if any - to challenge their fierce rivals next term.

The Gers have cruised to the Championship title this season, playing an expansive brand of football implemented by Warburton.

And Groves has questioned whether the Light Blues' boss will employ the same tactics against a similarly attack-minded side at Hampden Park.

"I’ll be interested to see if Mark Warburton has the same sort of philosophy where he pushes his two full-backs way up the pitch," the 50-year-old said on Friday's Colin Murray show.

"James Tavernier has got 14 goals from right-back and Lee Wallace has got five from left-back and they actually become like wingers, so in a massive game like this playing at Hampden, which is a huge pitch, is he going to play exactly the same way?

"Same thing with (Celtic boss) Ronny Deila is his team likes to play expansive football, they’re not two teams who like the cut and thrust, getting stuck in and the robust sort of Glasgow derbies so it’ll be interesting to see if the players stay nice and calm of they get carried away with the occasion."

Sunday's Old Firm derby is only the second since Rangers were demoted to the fourth tier in 2012.

The Gers already have two pieces of silverware in the trophy cabinet this season, having sealed the Championship and lifted the Petrofac Cup in the space of five days last week.

And Celtic remain in the hunt for a domestic double of their own, with the Bhoys currently eight points clear of Aberdeen at the top of the  Premiership.
