West Ham lost 2-0 against Everton at the London Stadium.
First-half goals from Kurt Zouma and Bernard secured all three points for Marco Silva’s men.
Marko Arnautovic was ineffective as West Ham had only one shot on target which was saved by Everton goalkeeper, Jordan Pickford.
However, Pellegrini is unhappy with his team lack of fighting spirit and tag their display against Everton as “worst home performance” and “worst performance of the year”.
Speaking after the match, Pellegrini said: “The complete game we played very badly,”
“We didn’t create chances in Everton’s box and conceded two goals.
“It was one of those bad days.
“It wasn’t only the worst home performance but the worst performance of the year.
“You can lose, but not like that – without fighting.”
