Jose Mourinho says top four a hard task for Chelsea next season

Chelsea manager Jose Mourinho believes his newly crowned Premier League champions will face a challenge just to secure a top-four finish next season owing to the top flight's competitiveness.

Chelsea claimed their first league title since 2010 on Sunday when Eden Hazard's goal on the cusp of half-time secured a 1-0 home win over Crystal Palace that gave them an unassailable lead at the top of the table.

Mourinho's side have dominated the division from starting gun to finish line, but with Manchester City, Manchester United, Arsenal and Liverpool all likely to strengthen during the close season, he knows the battle for Champions League qualification will be fierce in 2015-16.

"We have to try to be a strong team because if you are not a strong team, we have no chance to finish top four, which is the first target for the top teams in this country," he said.

"When you fight for the top four, you have chances to be champions, so we need to be strong again next year, to try to be a good team."

Mourinho has now won three Premier League titles, following back-to-back successes with Chelsea in 2005 and 2006 during his first stint at the club, but shied away from comparing those teams.

"This one is completely different," he said. "The Premier League is different, Chelsea is different, opponents are different.

"And my team, so many of them win the Premier League for the first time, which is something that they have to learn how to do."
