Ramires joined the Blues from Benfica in the summer for around £17million.
Alex told talkSPORT: “I think Ramires is a great guy, very humble and he never forgets his origins.
“This can only help him to settle here and I will also do my best to make sure he feels welcome – especially as he lives next door to me now so I spend a lot of time with him.
“He will grow here and I think he has everything to be a very good player and a very stable part of our squad.”
