Rangers legend Derek Johnstone believes Sean Goss and Greg Docherty will have a big say in the outcome of Sunday’s Old Firm clash at Ibrox – but admits the Gers’ defence still raises some “doubts.”

Goss and Docherty have been a huge part of the club’s recent success and have wowed fans with their performances in the middle of the park as the Light Blues have closed the gap on bitter rivals Celtic.

The dup are expected to start in central midfield for the Ibrox giants in Sunday’s Old Firm clash and Johnstone thinks they will have “big parts” to play against Brendan Rodgers’ side.

“There are still some doubts about this Rangers defence at times but in Greg Docherty and Sean Goss we have two very capable players in the middle of the park,” Johnstone said, as quoted by the Evening Times.

“They will have big parts to play and they have to stop the supply to Celtic’s strikers. Out wide, the two wingers have a role to play in their own half of the pitch as well.

“Docherty is perhaps the more industrious of the two midfielders, he can get back and defend and get forward as well, but Goss has been very impressive and has a terrific range of passing.”

A win for the Gers would see Graeme Murty’s side close to within three points of their rivals at the top of the table as the Gers look to mount a surprise title challenge.

The Light Blues were written off completely earlier in the season after falling to fourth in the league and sacking manager Pedro Caixinha but have undergone a remarkable revival under Murty to find themselves so close to the champions.

Football Insider verdict:

The midfield pair of Goss and Docherty have been really impressive in the last few weeks as the Gers have won six games on the spin and could help the Ibrox giants take a step towards an unlikely title success. Fans already want to see the duo in the Gers midfield for years to come if they can land Goss on a permanent deal from QPR. Goss and Docherty really complement each other in midfield and have given the Gers a nice balance, both in attack and defensively. If they can play like they have recently for Graeme Murty’s side they will give the Gers a great chance of taking a win.
