This was supposed to be all about Lionel Messi and Eden Hazard.
Antonio Conte sent Chelsea out with a front three without Alvaro Morata or Olivier Giroud, leaving Hazard as the Blues’ focal point of attack.
But everyone forgot about how dangerous Willian can be rampaging down the wings.
The only problem is, he is currently the unluckiest man in the Champions League.
Messi began the match by pulling all the strings for Barca as time after time he picked up the ball in midfield and drove right at the heart of Chelsea.
But, as the game went on, his less glamorous Brazilian opponent became the most dangerous player on the pitch.
And he proved it by slotting home a lovely curler 15 minutes into the second half.
First Willian left Ivan Rakitic eating dust as all the Croat could do was foul him as the Chelsea man flew past him.
Then came his first shot and the closest either team had come to scoring.
With possession clock reading 75-25 in Barcelona’s favour, Hazard fed Willian 30 yeards out.
He took two steps to the right and curled a wonderful shot past the stranded Marc-Ander ter Stegen.
But unfortunately it cannoned straight back off the right post and to safety.
Willian probably hoped that was all his bad luck out of the way for the night.
Just eight minutes later he picked up the ball in a similar position outside the D, shimmied onto his right and slammed a shot at goal.
The world came to a standstill, the crowd expecting to surge with cheers for a goal and everyone was stunned to see the ball rebound of the left post this time.
Willian looked understandably gutted as the second shot rolled away.
Barca have always been pretty lucky at Stamford Bridge.
