Zaha says he is driven to prove he was deserving of the chance of joining United originially.
He told the Mirror, “The only frustration was I would have liked to had more of an opportunity to show I was good enough for Manchester United . But I feel like that period has pushed me to still be relevant now.
“I'm still buzzing about the day when I actually met Sir Alex Ferguson and Sir Bobby Charlton. Even to this day. One of the greatest managers in the Premier League, and he's telling me: 'I want you to come to my team.' It was a no-brainer. I was a bit sad when I saw him leave, because he didn't tell me he was going to retire.
“There are so many people who have been in those predicaments when they've gone to top teams, haven't had chance to play and when they have left, you just don't hear of them. Thats what has driven me more to be like the top players.
“They prove it every game, why they are top players. I just had to show constantly that wasn't a fluke, I didn't win a raffle ticket and went to Manchester United. I am a good player. I will make sure I continue proving that."
