Holloway was Palace manager when Palace sold a young Zaha to Manchester United.
He recalled to Palace TV: “I didn't believe what I was being told at [co-owner] Stephen Browett's house. His family were saying: 'Wilf, he's just brilliant. He's just too good for the division.'
“Because I'd had some wingers who I thought were really good - Tom Ince and Matt Phillips - I thought: 'You can't be that good.' So I watched that game [v Blackburn Rovers] and he did things I didn't think were possible."
