London - Chelsea manager Jose Mourinho believes his newly crowned Premier League champions will face a challenge just to secure a top-four finish next season due to the English 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.
