Mourinho feels his players have now improved together.
He said: "We're all here today because we all work on the team. There are others who aren't here today that have also been part of a coaching staff that has given its all to help the players achieve success. We've all won and lost together. I said we would all either laugh or cry together in the end and we've eventually laughed because things went our way.
"I think we've had a very good season. We've grown as a team and as a group of people. We want to do better and improve. We've established difficult records and won the most important title. We've also been in the Champions League semifinals a second straight year, which means we're strong there also. We also had great respect for the Copa del Rey. We fought for the title. It's been a very good season and I believe it is impossible to improve on our numbers. We want to win the league title again next season, but we know it will be very difficult to earn these numbers again."
