Celtic midfielder Victor Wanyama says the club is desperate to reverse last weekend's shock League Cup loss to Kilmarnock.
The Hoops went down 1-0 at Hampden Park to miss out on the first piece of silverware of the season but the Kenyan ace is not about to let this Sunday's opportunity with Glasgow rivals Rangers at Ibrox pass them by.
"It was a very big game and a chance for me to win something. It was very important to me before the game and I was very disappointed at full-time when we lost.
"We have to step up now and concentrate on our next game.
"Hopefully we will be back to our best and can continue our run in the league. There's nothing we can do now. We just have to move on and put it out of our minds.
"We've all switched our minds to Sunday's game now and hopefully we can make up for the defeat against Rangers. ""I've learned a lot from this (the loss to Kilmarnock )," he told Celtic View.
