The Crystal Palace winger signed for United in the January transfer window and will join up with his new team in the summer, and Redknapp, who commentates on Premier League football for Sky Sports, says that he is looking forward to Zaha's arrival in the division.
"I can't wait for him to get to Manchester United, where he will thrive," Redknapp wrote in his column in the Daily Mail.
"He is maintaining his form for Palace and dazzled Leeds with his pace and direct runs. I know of scouts who watched Zaha and recommended against signing him because he uses too many tricks."
Zaha signed for the Premier League leaders for a reported £15m.
