Meanwhile, Mata insists Chelsea are still alive in Europe despite Ezequiel Lavezzi and Edinson Cavani swinging the tie in the Italians' favour after his opener.
The Blues have their work cut out to make the quarter-finals but Mata is confident of turning things around at Stamford Bridge in three weeks.
He said: 'We are not dead. It will not be easy for us but I think we can do it.
'At Stamford Bridge the atmosphere is going to be very intense and full of supporters supporting us. It will be a very difficult game but we will have to give our best.
