Emerson Hyndman insists Rangers are now a more accomplished team that the side that drew with Celtic last month.
In his last act as caretaker manager, Graeme Murty masterminded a share of the spoils at Celtic Park on March 12 after Clint Hill grabbed a late equaliser to cancel out Stuart Armstrong’s first half strike.
Since then, new manager Pedro Caixinha has presided over five undefeated matches from the dugout, winning three.
Speaking to Sky Sports, he said: “We’ve got a permanent manager now and things are a bit more settled down, we’ve had quite a few games under him now and we all feel comfortable with our roles and our positions.
“I would say definitely we go into this a bit more comfortable as a group.
“Obviously they’ve had a good season, you can’t doubt that but we’re going into this game thinking about ourselves mainly, and we’ll be prepared in every possible way.
“We’ll be organised but at the same time we want to show our quality. It’s a cup game, so it’s one-off and on the day we’re looking to win it.”
