He said on Rio Ferdinand Presents: "When I was playing against strikers every week, on the Thursday or Friday before the game, I said to the analyst, 'Fill the iPad up with the strikers that I'm playing against, and I want to see their best clips and their moments—goals and assists, etc'."
Ferdinand then asked: "Is that what you're doing?"
To which he replied: "Yeah, yeah, of course. It's important. We have a group on WhatsApp. With all the defenders, they send clips of the strikers, their movements, their runs. And outside of that. I have one person who's doing really a lot of clips on the striker for me to know. I had already someone in Lille, so I keep working with him. [I am] especially looking where to run, for example if the defender has the ball, for a long pass. Or for a cross with the first or second ball, everything is really important."
