The Sun says the Blues are unbeaten in all three competitive games they have played against the Spanish giants. Boss Tuchel should get his squad to read through the history books to give them a boost.
In 1971 the two teams met in the Uefa European Cup Winners Cup. The first game finished 1-1 with the sides unable to be separated after extra-time. Peter Osgood fired the Blues 1-0 up on 56 minutes but Zoco sent the game to a replay with a 90th-minute equaliser.
But it was Dave Sexton's boys celebrating in the second game with goals from John Dempsey and Osgood again securing a 2-1 triumph. Sebastian Fleitas netted a consolation for the Spaniards.
Real Madrid set up a fourth meeting against Chelsea after they eased their way past Liverpool. A 3-1 Bernabeu win saw the Premier League champions with it all to do - and they failed to fire in a 0-0 second-leg draw.
