Rangers midfield ace Ryan Jack, insists the Ibrox side aren’t even at their best yet – the midfielder grabbed two goals as Rangers swept Ross County aside 4-0.
Jack has called for calm and caution because they have no catalogue of success in the past few seasons.
He said: “We are going well and there is no doubt we are a good side but we have not done anything and not won anything yet.
“We know where we want to be. Sunday is another big game as we want to get to a cup final and we want to get the fans to a cup final.
“Of course it hurt to lose at the same stage last season but we cannot think too much in the past.
“We have a different squad, our group of players are a lot stronger and it’s a different season. We are playing well, there is nothing for us to fear and we are looking forward to the game against Hearts.
“We will have another big support there and are excited about trying to get the club to the Final. That’s the platform on which we want to play.”
