In comments reported by Football London, Manuel Pellegrini has conceded that Marko Arnautovic did not have the best game in West Ham's stunning win against Huddersfield as the Hammers boss was asked about the fans booing the Austrian.
In a remarkable game at the London Stadium, the Irons edged a seven-goal thriller, but only after going in the final 15 minutes 3-1 behind. But a goal from Angelo Ogbonna and a brace from Javier Hernandez turned the game around and pushed the Terriers closer to relegation.
The turnaround was only sparked by some of Pellegrini's substitutions, particularly the introduction of Samir Nasri shortly before he decided to take Arnautovic off. And it was as the forward's number appeared on the board that the fans vented their frustration at his performance.
And after the game, Pellegrini commented on the booing of Arnautovic.
"I think that, as every player who is not at their best, Marko did not have the best game," he said, as reported by Football London. "When Samir Nasri came as a playmaker, he gave more balls to the attackers. The complete team played very bad during most part of the game, conceding two goals from set pieces and after that, the complete team improved and we changed the score."
The West Ham fans have not seen the best of the 29-year-old for a while now. It is more than two months since he last scored in any competition, while he has only provided one assist in his last seven games.
In fairness, Arnautovic was making his first start since January. But given the slightly bizarre events of the most recent transfer window (via Sky Sports), he arguably has plenty to prove to get all of the fans back on side.
And after a lacklustre performance on Saturday, it appears that the former Stoke City man has given himself an even tougher task trying to prove that he can get back to his best with West Ham.
