Juan Mata's goal was lucky - Roberto Di Matteo

Chelsea caretaker manager Roberto di Matteo says the Blues were on the "lucky end" of a refereeing decision when Martin Atkinson awarded Chelsea a second goal, even though Juan Mata's shot did not appear to have crossed the line.

Chelsea thrashed Tottenham 5-1 to reach the FA Cup final , giving Chelsea, according to Di Matteo, a boost ahead of their Champions League semi-final clash against Barcelona.
