Ferdinand says Bale will be under huge pressure to deliver.
"Who's going to take the free-kicks? The corners? The penalties? At Tottenham he got goals from them. Take those away and he loses 9-10 goals from last season.
"If he's not taking those set-pieces he's got to get those goals from somewhere else. And if Ronaldo is getting 50 goals a season, and Bale cost more than Ronaldo, how many must Bale get to justify himself?
"This is the kind of thing he's had to think about before going there. People will say it's an easy decision to sign for Real, but when you start thinking about possible downsides, it takes some bravery.
"He's not going to be able to hide. And I speak to Ronny [Ronaldo] a lot, so I know."
