Chelsea caretaker boss Roberto Di Matteo says he won't be taking Champions League opponents Benfica lightly.

If they manage to beat the Portuguese, Chelsea will face the winners of Barcelona and AC Milan.

"Are you writing off AC Milan, the leaders of Serie A, as easy as that?" Chelsea's interim manager asked those anxious to leap beyond Benfica and discuss the prospect of meeting Lionel Messi in the semis or Jose Mourinho in the final.

"You're well ahead in the future. You speculate if you want. I'm not. When you get to the last eight every draw is difficult.

"Benfica have good players like Gaitan and Luisao but they're a good unit. They won Manchester United's group."
