Ferguson should mind his own business, Di Matteo says
Chelsea manager Roberto Di Matteo has urged Manchester United boss Sir Alex Ferguson to focus on his own side rather than comment on the affairs of others, ESPN.co.uk reported.
"It's a free country where everybody has the freedom of speech," Di Matteo said in reference to Ferguson's comments on Clattenburg.
"We'll take into consideration what other people say and use it as a motivational tool for ourselves.
"He likes to talk about other clubs. We tend not to. I'll leave it up to him."
