Chelsea overcome unique Barcelona test - Roberto Di Matteo

Chelsea interim manager Roberto di Matteo says beating Champions League title-holders Barcelona 1-0 at Stamford Bridge was one of his club's biggest challenges for many years.

Didier Drogba struck in first-half injury-time to give the Blues an advantage to protect at the Nou Camp in the semi-final second leg next Tuesday.

However, the Blues boss rejects Pep Guardiola's opinion that Chelsea are now favourites to go through to the final, saying it is "50-50".
