Chelsea boss Jose Mourinho has congratulated Walter Mazzarri on taking the Inter Milan job.
At Inter, Mou often clashed with then-Napoli boss Mazzarri in the media.
"At the start of his Nerazzurri adventure, Walter Mazzarri received well wishes from Jose Mourinho who - via technical director Marco Branca - wanted to wish the Coach luck on the Inter bench," read a statement.
"In turn, Mazzarri thanked him and wished the Portuguese manager the best as he begins his journey at Chelsea.
"This confirms the reciprocal respect between the two Coaches who will meet up leading their teams during the summer American tour."
