Manchester United boss Jose Mourinho says there'll be no resting on their laurels after victory over Chelsea.
Mourinho admits they need to find more "quality" this summer.
He revealed he wants to strengthen his squad this summer in the aftermath of victory: "I think we need a little bit more quality and different qualities in some positions for next season to make the squad stronger but in terms of character and the human side of the group, I have one of the best groups ever."
He added: "Normally you win the title if you are 22 matches unbeaten and we are struggling to finish top four.
"But it's a great feeling to know that it's difficult for us to lose a match, people fight until the end."
