Chelsea v Barcelona: Top 3 key clashes that could decide the result 

#1 Eden Hazard v Gerard Pique

Pique's vast experience at this level will come in handy against Chelsea

There has been talk that Conte will set up his side in a 3-5-1-1 formation, similar to how he did away to Atletico Madrid earlier in the season, and if he does, Eden Hazard will probably play in this hole behind Morata.

Depending on how aggressive Chelsea are in taking the game to their opponents, Hazard may find himself quite isolated in the game, especially if Barcelona are on form with their possession and passing. His dribbling skills and ability of regularly beating his marker will be of vital importance to Chelsea's fortunes on the attack.

On the other hand, Gerard Pique has been one of the world's best centre-backs for years now, but doesn't have the pace to match Hazard if a break is on, so he'll have to be attentive throughout the game.

With right-back Sergi Roberto suspect defensively, given his tendency to make runs forward in support of Barcelona's attack, Hazard may look to exploit this side of the pitch, so it will be up to Pique to watch this area carefully.

He won't want to get involved in a foot race with the Belgian playmaker, so Pique will look to stick close to Hazard and suffocate him from playing his football. It will be a game of tight margins, with no room for error, meaning Pique's concentration will have to be at its strongest if Hazard is to be kept quiet.
