"Madrid always want the best. Tottenham is a very amicable club, but first we must see who our new coach will be and after that we will begin to arrange our new squad," he told Marca.
"I think the same as if we were to have a tennis team and Rafael Nadal asked me for these millions. For players like this - the investment they generate you and the revenue they produce, you can give everything to try and get them.

"But I repeat, we have a long list, but there will be one particular player, of course."
