The Arsenal legend believes the Portuguese boss has signed the perfect players for his side.
It is also their first championship since Mourinho returned to the club last season, with him also having added the Capital One Cup earlier in the season.
Now, Henry has praised the transfer business carried out by the Portuguese manager in that period.
With Financial Fair Play you can’t do what you used to do – so for the likes of Chelsea it’s more difficult to spend,” he said.
“He [Mourinho] wanted to get rid of some players here that were not ‘his’ players. He got rid of Juan Mata – people argued with that – David Luiz, Samuel Eto’o and Fernando Torres left. Sometimes it’s not about money and what you do with it, it’s who you are buying.”
The Blues have been impressive in the transfer business in recent seasons, often employing a one in, one out policy so as to remain in line with FFP restrictions.
They have however been able to continue to bring in big name signings and not break the rules, with Juan Cuadrado a big money move in the January transfer window. It is the signing of midfielder Nemanja Matic however, that has come in for particular praise.
“Nemanja Matic, for me, was as important as Fabregas,” he added.
“He went out there to buy the players Chelsea were missing, whether they were big money or not. You have to give him credit because he had to make sure he could readjust that Chelsea side that he took on board, to make it his Chelsea side.”
