Tevez could make his debut in a friendly at Dunfermline tonight.
Ferdinand said: “Over the first two days, he’s already shown glimpses of what he’s about. He’s been very impressive.
“I know Kia Joorabchian and Pini Zahavi and they’ve been singing his praises for years, before I’d even laid eyes on him.
“And my brother has always said he’s a fantastic footballer — he thinks he’ll be great for us.”
Ferdinand added: “The lads are very excited — we’re like fans in that we look forward to the new players coming in.
“Wayne Rooney and Tevez would be exciting.
“But it’s not just them, the manager has loads of different combinations.”
