Changes were inevitable at Stamford Bridge this summer, with Mourinho's first season back at the helm having failed to deliver major silverware.
That issue has been addressed, with a number of players moved in and out.
Romelu Lukaku became the latest to depart on Wednesday, as he completed a £28million move to Everton, but that sale was sanctioned on the back of deals for Diego Costa and the returning Didier Drogba.
It is not just up front that changes have been made, though, with Filipe Luis drafted in to cover the loss of Ashley Cole at left-back and World Cup winner Cesc Fabregas adding creativity and experience to the midfield unit.
Mourinho is delighted to have completed his business early and believes that a group which blends seasoned professionals with exciting youngsters will be extremely competitive in 2014/15.
He said: "We are so happy with the squad we have.
"We feel that the correct squad is exactly this type of squad we have, with people like Didier and John Terry, but at the same time people like (Andreas) Christensen and (Nathan) Ake.
"We have the squad we want and, I repeat, the club was fantastic in the way they worked so hard and so fast to get Diego, Filipe and Fabregas."
The last thing Jose needs is lessons from spurs fans, lol. I hope Jose hasn't finished with bringing new players as I feel the with what we have at the moment is not good enough for the whole season especially if there are injuries.- crow
