'You can be an underdog and win'published at 13:23 Greenwich Mean Time 1 February 2015
"I do think we are of a level right now of the Premiership teams we have beaten and over the course of a season we could match them, but I don't think we could match Celtic," says Rangers striker Kris Boyd.
"We understand where we are, but you just need to look at the FA Cup at the weekend. You can be an underdog and go and win games.
Image source, SNS"We feel we have got good players and we can cause them problems. We have a group of hard working people who will go there and give our best and hopefully that is good enough to get us over the finish line, but we'll not get carried away."
'It will be fun'published at 13:21 Greenwich Mean Time 1 February 2015

"You can feel in the city that a big game is coming up. You hear it wherever you go - you hear it in the grocery store."
