Rangers boss Mark Warburton is confident his side have addressed the problems that saw them lose out to St Johnstone as they prepare to face Premiership opposition again in the Scottish Cup.

A determined Perth side recorded a 3-1 win at Ibrox, knocking Rangers out of the League Cup in the process.

But Warburton insists that his team have resolved those issues as they prepare to face top flight opposition for the second time this season.

"We saw games where teams had nine or 10 men behind the ball and it's very hard to break down" the Rangers boss told the press.

"We had to show patience and when we didn't show patience and lost our shape, we were vulnerable.

"If we push too many men forward and expose ourselves in key areas, then we are going to be in trouble. In a couple of games that was the case, but hopefully we have corrected that. "

The clash carries added significance, with former Rangers star Lee McCulloch set to feature in the opposition dugout as he leads Kilmarnock in his managerial debut.

Warburton is adamant that McCulloch and former Gers pair Kris Boyd and Steven Smith, will receive a warm welcome on Saturday.

"I hope very much that they get the right reception. They've served the club and I obviously wasn't here before the start of this season but in Kris, Lee and Steven you have good pros and they deserve the right reception."

Speaking about his counterpart, Warburton joked "I've had a cup of tea with him.

"Lee is a man that's played over 300 games for the club, scored 70+ goals, been the captain, played every position bar goalkeeper so he has had a tremendous playing career.

"I'm full of respect for that, and I'm sure he'll bring a side that's hungry to perform and keen to impress."

Kenny Miller is well aware of McCulloch's attitude as a player, and believes his former team-mate has a tough task ahead of him.

"I always knew he wanted to move into that side of the game - probably not as quickly as he’s having to now, to be honest" reflected Miller.

"It’s a tough position to get put into, when you’re the assistant manager of a football club and you’re asked to take over, it’s not ideal.

"I’m sure he will step up to the plate and deal with it because these opportunities don’t arise every day."

Miller, like his manager, stressed the importance of Rangers focusing on their own abilities, and believes they can be respectful but thorough in their performance at the weekend.

"We give every team the respect that they deserve" Miller said.

"They’ve got some good players, they’ve got areas we can exploit, that’s the things we work on and we’ll be more than prepared for them on Saturday.
