Rangers face Celtic next weekend in the Scottish Cup semi-final.
Gers face Celtic in a highly-anticipated Scottish Cup semi-final at Hampden Park next weekend.
The Old Firm duo have not met since the Hoops recorded a 2-0 win over the Ibrox club in the League Cup semi-final showdown last season - a game that was relatively easy for Ronny Deila’s men.
But Rangers have improved immensely this season under Mark Warburton, and striker Miller responded confidently when asked whether the first division champions can upstage their rivals.
“If we turn up we know we are a match for them. We know we can beat anyone if we turn up and do what we do. Celtic will be a big step up because they are top of the league and probably going to win it – and that makes them the best team in the country,” Miller told Herald Scotland.
“We play a level below so it’s hard to judge. They play a higher level of opposition every week and that’s not disrespectful. It’s just a fact. We are going to have to make a step up – but we are capable of doing that.”
Rangers will head into the encounter with plenty of confidence after winning the Scottish first division and the Petrofac Training Cup via a 4-0 win over Peterhead at Hampden Park in the last week.
But they may have to do it the hard way against Celtic, with top scorer Martin Waghorn battling for fitness.
Ronny Deila’s side are closing in on a fifth straight Scottish Premiership title following a 2-1 win over Motherwell at the weekend and they will head into the fixture as favourites to beat their Glasgow rivals.
