Antonio Conte doesn't hide it: He expects Chelsea to struggle against Barcelona at the Camp Nou.
Conte said: "You must be excited to play this kind of game at the Nou Camp. It will be a very hard game".
Chelsea will be looking for every single chance to counter and that is where Barca's possession game can be unsafe for the Catalans themselves.
Lionel Messi led the way as he opened the scoring early on, with both his goals going through Tibaut Courtois' legs.
Barcelona are optimistic for an action pact 90 minutes as two of their key players have returned for tonight's Champions League clash with Chelsea.
He also tackled Cesc Fabregas in teeing up Dembele's sumptuous strike.

"It's not nice to start an evening like that". The weakest point is between the legs for a goalkeeper. "We did this, but we made a mistake and paid heavily for it".
Conte described the start as "terrible", but was pleased with the response.
"But Chelsea happened to cross our path many times and I have many strong memories of meeting them".
"A fantastic player moved the final result".
His form, however, has dipped as the season has progressed and h'es been unable to find the back of the net in all competitions since the Boxing Day Premier League fixture against Brighton.
Ahead of facing the reigning Premier League champions, talk turned to whether Messi could join a side like Chelsea but Busquets was doubtful.
Alonso was in the spotlight once again in the fourth minute of the second half.
Barcelona, on the other hand, are flying at the top of La Liga, thanks to a 1-0 victory over closest challengers Atletico Madrid two weeks ago.
"I've played against Messi a lot of times", he said. "If they score we could be really suffering for that", he said.
Messi missed last Saturday's win at Malaga to attend the birth of his third child and seized control of the tie on his return.
Barca have set the standard in recent years for the most glittering style of football but Ernesto Valverde has instilled a new style this season, built on resilience, organisation and hard graft. He forces himself to do that.
"We're lucky enough to be seeing something that will go down in history".
