Chelsea midfielder Oscar has provided Blues fans with another reason to beam throughout the international break, signing a new contract that commits his future to the Premier League leaders until 2019.
Oscar's previous deal expired in 2017 and Chelsea were clearly keen to make sure the Brazilian playmaker didn't become a genuine transfer target for any of their rivals across the continent, which is perfectly understandable given their impressive start to the season.
The 23-year-old's reward for excellent form despite a workload that shows no sign of slowing down is a two-year contract extension, which no doubt comes under improved terms.
Selecao star makes number 10 role his own
There were some doubts going into the new campaign over how Mourinho would deploy Oscar, a tireless worker capable of playing both in an advanced central role or out wide if required.
Mourinho would have also been within his rights to be careful with Oscar in terms of its workload, after a gruelling 18 months which has seen the Selecao star play almost interrupted for club and country.
Blues tie down another star for his peak years
Any fears over Oscar's stamina have been put to bed by the South American star's level of performance so far this season, with a technically-superb strike against Queens Park Rangers the pick of his four goals so far this season.
In a statement on Chelsea's official website confirming the deal Oscar shared his delight with life in West London, declaring: "I am so happy because I love playing for Chelsea and living in England.
"I have enjoyed playing here for two years, and now I have five more, so I am very happy."
Challenge now to win silverware
Mourinho's men look in terrific shape to dominate domestically this season and beyond, with Oscar's new deal just the latest piece of that puzzle.
Chelsea will now surely turn their attention to getting Eden Hazard to follow suit, part of a structured plan to get the vast majority of their squad committed to a vision of ruling the roost for years to come.
