If Mourinho stays at Madrid for a decade, I could easily see a Madrid - Chelsea rivalry coming in. But on the topic, yeah it seems to me like it is. They don't like playing against us, and neither do we. Has been some epic matches over the past decade. And now that we are getting better players, Chelsea this time might not be like the Chelsea of this year but more of a Chelsea of years back, where it was a close game between both teams. Once that happens, then I will say for most people it will consider a true classic.
