5 things to look forward to when Chelsea take on Barcelona 

#3 Messi vs Hazard

The two are yet to face off in competitive club football

They are their team's heartbeat, the creative force that drives Barcelona and Chelsea respectively and are superstars in their own rights. Diminutive, yet lethal players, Messi and Hazard skip past players with ease, before finishing the move with a well-deserved goal.

Both are immensely difficult to mark and contain, because of their low centre of gravity. The last time they met each other as opponents was in the 2014 FIFA World Cup, which Argentina won by a 1-0 margin courtesy of a Gonzalo Higuain goal.

Whoever has a bigger impact could end up on the winning side come full-time.
