It was always going to be hard for Besiktas to progress beyond the Bavarian giants, but a 16-minute red card for defender Domagoj Vida made it nay on impossible for the Turkish side to get anything from this game.
There is a general acceptance that Conte will part ways with Chelsea at the end of the season given the tough times the club has seen this campaign.
But after Christensen's pass across his own box failed to find Cesc Fabregas's feet in midfield, while Cesar Azpilicueta was also unable to get a foot to the ball, Iniesta intercepted it before cleverly finding Messi. At the helm, were Iniesta and Messi.
"The result is good, they have to go there to score a goal", he added. The following week a visit to the Etihad to take on champions-elect Manchester City will provide perhaps the sternest examination yet of the Blues' recently regained resilience and belief. It was at that time that Conte's decision to play without a designated striker looked like a wrong ploy to go with.
"Young Andreas Christensen played very well and made that pass across the box - you don't do that as a defender with players of the magnitude on the pitch".More news: Pakistan eyes enhanced ties with Russian Federation in balancing USA influence
Barca then went on to dominate possession for a large spell of the first half with their control of the ball reaching 80 percent at one stage. Despite his sub-par performance, Chelsea contained Barça well for most of the game, playing with a high intensity, pressing effectively and keeping a solid defensive shape.
Ever since he took David Luiz's place in the middle of Chelsea's back three, Andrea Christensen has shown why he belongs at Chelsea and not out on loan. Messi and Luis Suarez had been comfortably contained, and the hosts had created several chances, notably through Willian, who rattled the post twice in the first half. But Barcelona continued with their game plan which was effectively worked out by the Blues.
Willian saw enough in Chelsea's performance at Stamford Bridge to suggest they can upset the odds in the second leg. Having that extra man in midfield helped in defending whereas having a fluid attacking three helped Chelsea in transitions.
But against a team of Chelsea's quality, Barcelona risk being picked off and it would be foolish to dismiss the goalscoring prospects of a team containing the likes of Eden Hazard, Willian, Pedro and Alvaro Morata.
