Disappointed Spurs supporter, but Chelsea won the league fair and square. Their away form far superior to Tottenham's. No shame losing out to most consistent team this season. Our injuries and European campaign might have had an effect overall but we have had a great season.

Chelsea boss Antonio Conte: "That decision changed our season. We had to change and find a new suit for our team. In my mind there was this option to play a 3-4-3 because I knew I had the players to do that.
"We were not lucky, we did a great job. It's important to rest. It is a great season but now we can win the FA Cup.
"Every game I feel like I have played with my players! I show my passion and my will, my desire to stay with my players in every moment of the game. This is me, I am this.
"In the present, in the past, I stay with my players in positive and negative situations. We won this title together."

Chelsea manager Antonio Conte on Sky Sports: "Thank you, thank you. this is a great achievement for the players. I thank them for their commitment and work rate. They show me a great attitude to try to do something great this season. After this win we must be happy, we must be pleased.
"I thought that Hazard and Pedro were tired and we needed more energy. Michy paid me a lot with this change! It was great. It wasn't easy for me to arrive in England and try different habits, a different language and inherit players after a bad season."

Back in August, few would have predicted the relative ease with which Chelsea have regained the Premier League title.
With a new manager in Antonio Conte, and many of the same players who lifted the trophy in 2015, the Blues have been crowned English champions with two games to spare.
But how well do you remember the pivotal moments on their way to success? Time to put yourself to the test.

Antonio Conte's transformation of Chelsea from fallen champions to Premier League title winners inside 12 months was completed with victory at West Bromwich Albion - a remarkable success story in his first season at Stamford Bridge.
The 47-year-old inherited a squad that had declined from domestic superpower to mid-table mediocrity amid acrimony and the sacking of title-winning manager Jose Mourinho. But he has shown the personality, tactical brilliance and sure touch to put them back at the top of the English game.
So how has the charismatic Italian achieved what many inside Stamford Bridge regard as a miraculous rejuvenation of fortunes to return the Premier League crown to Chelsea?

Chelsea defender Gary Cahill: "You have to cherish these moments, you work so hard all season to be where we are. Consistently we have been the best team in the league. There is no better feeling in football.

It is huge.
Pep's job at Manchester City was a bigger job, Chelsea had won the league, they were winners.
But tactically, individually, what Conte has done with these players and to bring them together is sensational.
