Manager Jose Mourinho praised Chelsea's "perfect game" as they beat Swansea 5-0 but warned his players they must win titles if they want to be remembered.

First-half doubles by Oscar and Diego Costa and a late Andre Schurrle goal moved the Premier League leaders five points clear of Manchester City.

"It was a perfect game - everything went in our direction," Mourinho said.

"But there is no history without titles so if we play fantastic and don't win cups no-one will remember this team."

Nearest challengers City have a chance to reduce the gap to two points when they host Arsenal on Sunday.

And Mourinho would not entertain suggestions that the win in Wales increased the pressure on Manuel Pellegrini's title challengers.

"I don't think they feel it," the Chelsea manager said. "They have to win but they know that.

"We don't feel pressure, we feel responsibility. And for a team like them with the experience they have - much more than us - it's not a problem.

"This team is a young team with lots of years in front of them, but we are trying this season to make some history by winning something."

During his first stint in charge, Mourinho led Chelsea to the 2004-05 Premier League title with a record 95 points and also won the League Cup in his debut season.

The Stamford Bridge side retained their league crown the following year.

And in Mourinho's third season, Chelsea won an FA Cup and League Cup double before he left in September 2007 amid claims of a rift with owner Roman Abramovich.

After returning to Chelsea in June 2013, the Portuguese failed to win a trophy in his first season back.

They finished third - four points behind champions City - in the Premier League and were beaten by Pellegrini's side in the last 16 of the FA Cup.
