Chelsea facing benfica is not going to be an easy task for them if not for any reason but because Jose mourinho will be trying to prove a point. Benfica coach Bruno lage was sacked few days ago after a terrible defeat by qarabag and won't be willing to accommodate another lost in their next game against Chelsea in the coming days and secondly the presence of a new coach requires an excellent performance just to protect his new job at the club. Apart from providing protection to his job, the new coach Jose mourinho is a high profile coach with a lot of achievement in his coaching career, so finding the best way to win won't be a difficult one for him.
It may not be an easy task for sure, but with team effort and with coaching strategies, I would say, they can win on the game. Let us see.
Chelsea, is the slight favorite here but they should not be too confident as Benfica is also strong. Just consider Pavlidis from Benfica. And you won't think that Chelsea can win easy on this match.
