Mourinho, whose side are six points clear at the top in Serie A but stumbled through the Champions League group stages, also remarked on Arsenal against AS Roma and Chelsea versus Juventus.

"The draw puts our championship against the English one, which is certainly richer with teams that have the chance to spend lots," he told Juve's website (www.juventus.com).

Roma coach Luciano Spalletti was untroubled by Arsenal.

"It seems that people want to talk about an unlucky draw. The draw has been really good," he told Roma's television channel. "They have ambitious youngsters and they will become great champions."
