Reigning English Premier League (EPL) champions Chelsea have lost 1-4 to Watford, their second straight EPL defeat and the hosts' first triumph of 2018. The decision by new Watford coach Javi Gracia to advance his lines created enormous problems for Chelsea here on Monday evening, reports Efe news agency. Chelsea's stumbles in their own end created openings for Richarlison and Gerard Deulofeu, playing for Watford on loan from Barcelona, and the pressure pushed Chelsea midfielder Tiemoue Bakayokoto to commit fouls that saw him sent off in the 30th minute for a second yellow card.
