Stephen Robinson’s side will take on Brendan Rodgers’s Celtic away from home at Celtic Park in the Scottish Premiership on Saturday afternoon.
Campbell is set to feature in midfield for the visiting team, and the 19-year-old midfielder is not worried about coming up against Brown.
Brown, 32, is one of the best midfielders in the Scottish Premiership and is playing well for Celtic at the moment.
“I am not going to show any fear to him because that would be a sign of weakness. I will get stuck in, do what I do and show, on the park, that he should be worrying about me, not me worrying about him.”
“What Scott Brown has done in the game is obviously brilliant,” added the youngster. “He has won a lot of trophies. Every player wants them and hopefully I can win as many as possible in my career.
“It’s part and parcel of the game to be tackling and getting on the ball. Obviously, he is good at that, he has made a career out of it. Hopefully I can emulate that and play to my strengths to get a good career."
Celtic will head into this afternoon’s match as favourites, and it is hard to see them drop all three points against Motherwell.
The Glasgow giants are on a record-breaking unbeaten run, and they should at least pick up a point at Celtic Park.
Brendan Rodgers’s side are at the top of the Scottish Premiership table at the moment with 34 points from 14 matches, while Motherwell are currently fifth in the standings with 23 points from 14 games.
