Robbie Neilson wants his Hearts stars to come through another "big test" at Ibrox this weekend.
But he knows his team are up against it as they look to leapfrog Rangers into top spot.
Hearts have been flying so far this season and are yet to taste defeat as they get set to take on the defending champions.
Steven Gerrard 's team, meanwhile, haven't quite hit the heights expected with their performances, but they remain at the head of the pack after eight games.
It means the league's top two will go head to head at Ibrox this weekend in one of the most heavily anticipated games of the season so far.
And while Neilson was reluctant to get ahead of himself on what it could mean for a potential title challenge, he urged his players to pass the "biggest test" they have faced so far this season.
Neilson told Sky Sports: "It's still early in the season, we're only eight games in, but we're both in a good position to go top of the league if we win.
"We know it's going to be difficult but we've got a group here who are looking forward to the game and hopefully go and give it a good shot.
"It's a massive one for us. First we look out for the Hibs games, then after that we look for the Old Firm games.
"Especially going through to Glasgow, both teams in good form at the top end of the league.
"We've got a good young group here who are hungry to do well. It's an opportunity for them to go and test themselves again.
"We've had eight big tests so far and come through with flying colours. Now it's the biggest one so far for us."
