Chelsea goalkeeper Kepa Arrizabalaga says only "hard work" will snap their slump after defeat at home to Southampton.

It took a trademark free-kick from Southampton's dead-ball specialist James Ward-Prowse to win Saturday's Premier League clash at Stamford Bridge.

"Everything is going against us right now, we are in a bad moment and we have to stick together," Kepa said, before being asked whether changes to the team affected the performance.

"We have a big squad, a lot of players and a lot of quality but the things they are not going well,' he responded, "but it is not because we changed six or five or one player, it is more general, we are not doing well, it is clear and we have to improve.

"It is time to stick together and time to work, work and work."
