Di Matteo’s side are firm favourites to advance to a last four clash against Barcelona or AC Milan after Salomon Kalou’s second half strike clinched a 1-0 win over Benfica in the first leg last week.
Benfica posed little threat to the Blues in Portugal, but Di Matteo is adamant the Lisbon club are capable of upsetting the odds at Stamford Bridge. “We won’t switch off. Only 50 per cent of the job has been done because qualification is over two games,” Di Matteo said.
“We have put ourselves in a good position but Benfica away from home are a very strong side and they are capable of scoring as well so there will be no complacency from our side at all. I think we’ve been battling very well in the last three weeks, we have shown that on several occasions.”
