Pep Guardiola has stressed that Manchester City must "keep improving" all the time despite being crowned Premier League champions.

On Sunday, the Citizens played their first game since Manchester United's 1-0 loss to West Bromwich Albion seven days earlier had handed them the title.

Man City delivered a five-star performance to secure an emphatic 5-0 win over Swansea City and Guardiola was pleased to see his players keep their foot on the gas.

"It was a happy atmosphere around the stadium, getting off the bus and of course the supporters," the Catalan coach told BBC Sport. "The most important thing was a good performance.

"You have to keep improving, if you think 'okay, we are already champions', we are done, you cannot play like the way we played today. So we spoke to the players in the week about that. If we are improving it will be good for the new season, finishing in a good way.

"When they had the ball we pressed so good and so intense and then when we had the ball we had to keep it moving, moving, moving, playing simply until we had the chance to play a final pass.

"Swansea have had good results under Carlos Carvalhal against Arsenal and Liverpool and that's why it was so important to focus, play well and score."

Man City wrap up their 2017-18 league programme with fixtures against Huddersfield Town, Brighton & Hove Albion and Southampton.
