Former Real Madrid president Ramon Calderon believes the Spanish side have an obligation to buy star players like Tottenham's Harry Kane.
Spurs managed a 1-1 draw in Tuesday’s Champions League clash against Los Blancos, and the man behind the Galacticos between 2006 and 2009 thinks Kane would fit right in.
"A club like Real Madrid is obliged to have important players so they can bring in new sponsors, brands, and keep generating more money so they can maintain their current status," Calderon told Reuters.
"That money helps you to invest, save and invest again. I suppose Madrid would like to sign Kane — it depends on a few things, such as the desires of the player and the coach, but without a doubt, he is an outstanding player.
"He would not be cheap, but when I signed Cristiano Ronaldo for €80 million everyone thought I was crazy – and look where we are now.
"€150 million is now seen as nothing, it's normal. We no longer know what the limit is."
