Zaha is currently playing on-loan at Palace before he formally joins United in June.
"Manchester United have bought potential,” Bright told talkSPORT. “He’s been so exciting these last couple of years and he’s got so much better.
“He potentially can be another Ronaldo. He’s got great skills. He can use both feet. He’s got excellent speed and great endurance as well. He’s learning and he’s played for England.
“He’s gone to the right club. You know you can’t hold onto someone like that and £10million plus add-ons is a good fee for him.”
