Wan-Bissaka, a graduate of Palace's academy like Zaha, followed in his footsteps when he sealed a £50m switch to United in the summer.
It didn't work out for Zaha at Old Trafford back in 2013 but that hasn't been the case so far for Wan-Bissaka, who has hit the ground running.
Asked during a Q&A with fans which player was the hardest to play against in training, he said: "Aaron. He is very good, so hard to get past him.
"Have I watched him at United? I've watched a few games, what I thought of him is what I thought before.
"Everything that people are saying now - calling him 'The Spider' - we knew before, it is just that he is playing in front of the world now.
"We were saying it all before but it is nice to see the world know it now."
