The Scot is a big fan of the young Portuguese coach.
"He deserves to be at a big club because of what he did at Porto," Moyes said.
"If you get to cup finals and win leagues and you are that successful, then you deserve the opportunity to get a big job and he has got one at Chelsea. He knows the situation, he has been there before and he earned his stripes at Porto.
"He is a student of the game, he has been around it, he found himself a job at Porto and made it look easy - but that is because of the hard work he has put in."
