Chelsea hosted Barcelona at Stamford Bridge in the first leg of the UEFA Champions League round of 16 matches on Tuesday night. While most individuals favoured the Blaugrana on paper, it was a rather different story in reality.Despite retaining a whopping 73 percent possession on the night, Barcelona failed to test Thibaut Courtois as the Camp Nou outfit managed only one shot on target. Chelsea, on the other hand, examined the discipline of the Barcelona defence repeatedly and came close to scoring on many occasions.Willian was unlucky to have scored only one goal in the game and was undoubtedly the best player on the pitch. His goal was cancelled out by Lionel Messi as the Argentine was finally able to score against Chelsea following a defensive error by Chelsea's Danish centre-back Andreas Christensen.This culminated in a 1-1 draw as the visitors were able to take an important away goal back to Camp Nou for the second leg. Let us now have a look at the five key stats from the game.#1 A man in formWillian was Chelsea's best player against BarcelonaWillian looks like a rejuvenated man for Chelsea as the Brazilian has been turning up with some important performances for the Blues of late.
