Manchester United boss Sir Alex Ferguson says Jose Mourinho is the biggest threat to an English club winning the Champions League this season.
Ferguson reckons England's big four will dominate the elite comp.
It is nine years since Mourinho last tasted a home Champions League defeat as a manager, spanning his years at FC Porto, Chelsea, Inter Milan and Real.
Ferguson said: "Jose is an exceptional manager. If anyone outside the Premier League is going to do well then it is Real Madrid."
