Former Chelsea striker Hernan Crespo says they must be wary facing Champions League opponents Juventus.

The two teams meet next week in the latest round of group games.

Crespo told Sportweek: "Unpredictable challenge, just a detail. I don't know the two teams well also because living in Brazil I can't follow everything well. I saw the first round and they had two convincing victories, they will certainly pass the group.

"Juve comes from the third revolution in 3 years: the hard core is there but it takes time, the fans must have patience. They lost the best, that is (Cristiano) Ronaldo, and now they have to find someone who scores the same goals. I have faith in (Paulo) Dybala, but maybe he has to grow under the character aspect. Then there is the (Fede) Chiesa: he has the same speed as his father, the same selfishness, he must be more effective."

The Argentine also stated: "I would like to take the field with Chelsea, a team with which I won a Premier League and a Community Shield. And then I always scored many goals against Juve."
