Stricken Glasgow Warriors skipper Al Kellock has urged his team-mates to do the double over Edinburgh at Scotstoun on New Year's Day.
Kellock, out of action with a torn bicep, issued a rallying call to his counterparts, who hold a narrow four-point lead after defeating Alan Solomons' men 20-16 at Murrayfield on Boxing Day in the first leg of the 1972 Cup.
"I am not the best spectator in the world but at the same time, although it is very frustrating, it could have been a lot worse," Kellock told the Evening Times.
"If this had happened at a similar stage a year back I would have missed last season's Six Nations, been stuck on 47 caps for Scotland and who knows, maybe I would never have got to 50.
"Of course I'd love to be out there at Scotstoun on Wednesday. It was bad enough sitting out the Murrayfield leg but it will be even more frustrating on New Year's Day.
"But you know over the period of my professional career I have been pretty lucky with injury so I'm trying to stay philosophical about it."
Edinburgh dominated much of the Murrayfield clash, but failed to make their ascendancy pay on the scoreboard, with the Warriors coming from behind to claim victory via an incisive Stuart Hogg try.
Kellock knows his side will need to improve markedly on their display at Scotstoun on Wednesday.
"We must start a lot better than we did at Murrayfield. It was really only in the last quarter that we started to get the Glasgow support involved and when we did they gave the boys the energy to get over the line," added Kellock.
"So I think at the start we are going to have to make sure we control our ball a lot better but I believe the boys deserve a lot of credit for the way they came back at Edinburgh.
"To be fair to them, they bossed things in the first half and really played on the front foot, but to our great credit we stuck with them, hung in there and eventually ground out the victory."
