Hearts manager Robbie Neilson aims to use their winning mentality to upset Celtic again.
Hearts have won all six matches this season ahead of the Premier Sports Cup second-round tie at Parkhead, including their league opener against Celtic.
“My mindset is still the same,” Neilson said. “We want to go there and win. We’re in the cup, we’ve got the chance to go and progress into the next round.
“We’ve got a really good team here, we need to make additions, there’s no doubt, to give us more strength in depth in the squad, but the first 11 to 14 players here are very, very good, so we go into it with a lot of confidence.”
Hearts earlier announced they had sold more than 12,000 season tickets and Neilson wants to build on the feelgood factor.
“We’re winning games, that’s the most important thing,” he said. “That’s what a football club is about. We’ve managed to win the first six games of the season and we need to continue it.
“The club’s had a difficult 18 months but it’s turning now and we’re starting to get the positivity back but we need to keep on winning to do that.
“Momentum is big. It affects the mentality of the players. We know that it can change quickly in football.
“The key generally if it goes the wrong way is to turn it around as quickly as you can. The players have managed to do that previously but we want to keep this winning mentality going as long as we can.”
