The Scottish club have not had the best start to their campaign in the Europa League, particulary after a 3-0 thrashing to the hands of RB Salzburg in their last outing.
Now they face their toughest test of the group, as they come up against a team that boasts the likes of Timo Werner and Yussuf Poulsen in their ranks.
Not only did they already have an impressive array of talent in their squad already, but they have been able to add to the squad over the summer due to the money earned by selling Naby Keita to Liverpool, something that McGregor is wary of.
"They've spent a bit of money as well so they'll be fancying themselves to go far in the competition. For us, we'll go there fully prepared and try to get something from the game in terms of both points and performance." the midfielder said ahead of the game.
"The competition speaks for itself and there are a lot of good teams in the Europa League. When you come into a competition like that everybody's got to be taken seriously, regardless of whether they're first or third seed.
"You obviously show the team the respect they deserve but you get after them as well and hopefully try to implement our game-plan."
