Ferdinand believes the 24-year-old Ecuador international can get even better.
Valencia scored his first goal for the club agaisnt Bolton last week and scored his first Champions League goal in the 1-0 win over CSKA Moscow on Wednesday night.
“I think everyone is very pleased with what Antonio has done,” said Ferdinand.
“He’s a really humble and quiet lad. He comes in, does his work and goes home.
“He is from the Paul Scholes mould of embracing hype and attention but he’s the most confident guy on the football field and he’s been very impressive since he arrived.
“He is always available, always backing himself on the ball and doesn’t mind a bit of contact. He is a strong lad and that’s what you want.
“He’s playing very well and I’m sure he will keep improving and keep scoring goals.”
