I feel for Robbie
The Chelsea star insisted Di Matteos dramatic double winning the Champions League and FA Cup last season deserved the utmost respect and recognition.
But RDM was ruthlessly axed instead meaning midfielder Mata, 24, faces Fulham tonight working for his third manager in less than 18 months at Stamford Bridge.
He said: Roberto won two trophies in just nine months which is very difficult to do, so you have to recognise the job he did.
But he has been sacked thats how hard and unjust football is.
Just six months ago we were celebrating having won the Champions League.
Ill always remember the joy of our fans after we won the FA Cup and Champions League. Seeing thousands of people packing the streets to celebrate the trophies with the team is something Ill never forget.
But Mata, who was brought to Chelsea by Andre Villas-Boas, does not expect Di Matteo to be on the sidelines for long.
He added: Hes a very good coach and a legend at Chelsea, people have such a lot of affection for him.
Yes, there were hard and difficult moments, as there can be at any club, but they were more than made up for.
And Im sure hell soon have the opportunity to coach again.
