Real Madrid coach Carlo Ancelotti admits PSG are not in the same class.

Ancelotti left the French mega spenders this summer.

"The ambition is the same. PSG is another great team, but the difference is that Real Madrid is the best club in the history of football, and it's difficult to beat history. PSG is taking great strides towards being a great side, they have invested a lot of money in great players but making history takes time. Real Madrid have forged their history over many years," explained Ancelotti.
