Erik ten Hag says there is lots more work to do this season as Manchester United return to action for the first time since winning the Carabao Cup.
The Red Devils host West Ham in the FA Cup fifth round, three days after securing a first trophy in six years.
Asked if the celebrations continued after Sunday's win over Newcastle at Wembley, the manager said: "No. Nothing beyond. Get back to work."
United, third in the Premier League, are also in the Europa League last 16.
