Chelsea defender Kalidou Koulibaly joins Al-Hilal after disappointing season at Stamford Bridge

The Senegal International, Kalidou Koulibaly put pen to paper on a lucrative deal with Saudi side Al Hilal, bringing an end to a short and utterly disappointing season in West London.

The former Napoli man started his Chelsea career brightly but soon became one of the club's underperforming players, making mistake after mistake and struggling to find any kind of consistency.

He becomes Al Hilal's second high-profile signing this summer after the oil-rich club added Wolves midfielder Ruben Neves to their ranks.
