United were twice behind but managed to restore parity on both occasions thanks to goals from homecoming hero Shinji Kagawa - a graduate of Cerezo's famed youth system - and Zaha's 90th minute effort.
Moyes told MUTV: "Wilfried has done well. He's done well in the games. He's quite quiet and still getting to know everybody. I think he's performed well. He's had an impact in the games. We just want to try and bring him along nicely.
"I think tonight will help him. He's showed players he can make things happen. At Manchester United we want all players to score goals and he's come up with an important goal in the last minute."
