Wesley Fofana was the villain for Chelsea as they lost 4-1 to Manchester United in a Premier League clash at Old Trafford on Thursday night.
Fofana fouled Bruno Fernandes in the box before his error led to another goal by Marcus Rashford to seal another nightmare outing for the Blues under interim boss Frank Lampard.
Manchester United secured Champions League football for next season after the win.
Casemiro headed the hosts in front, with Anthony Martial sweeping in Jadon Sancho’s pass from close range to double their advantage.
Bruno Fernandes added United’s third from the penalty spot, and Marcus Rashford scored a fourth before Joao Felix’s late consolation for the Blues.
Chelsea are 12th with 43 points. The Blues will not play any European competition next season and will finish the season in their worst position since 1994.
