Chelsea manager Roberto Di Matteo said “It is a danger. This is half-time and we’re leading 1-0. But a 1-0 lead is basically nothing,” the Italian said. ”

“Our players are aware of this, and we’ll have to go into this game with the right attitude, the same attitude as against Napoli (when they came from behind to win the Round of 16 tie).

“Nothing has been done yet. We’re aware of that. We need to go and qualify for the next round.”
