Chelsea vs Barcelona: Sky Sports pundit Charlie Nicholas makes Champions League prediction
Chelsea have a real chance of beating Barcelona if they keep Lionel Messi quiet
"This is a 50/50 one for me. This Barcelona side are still nowhere near their best and Ernesto Valverde has not adapted to the Barcelona style.
"Selling Neymar was obviously a blow and Luis Suarez and Lionel Messi have suffered because of that.
"Gerard Deulofeu is not up to it so teams can get away with putting two men on Messi and Chelsea can do that with their system. Ousmane Dembele might be back and fit and that would make a difference.
"But, while they have improved a bit defensively, you can still go at their defence and I think Chelsea have a seriously decent chance if they can manage Messi."
