West Ham are suffering an injury crisis and are without up to seven key players.
"My first thought is for my player at the end, Amartey".
West Ham United manager Manuel Pellegrini says he has complete faith in Grady Diangana, who made his first Premier League start in the 1-1 draw against Leicester City. "I think he played a good game and must continue taking his chances".
'He has stomach problems, we will see if he can come back.
"It was a tough game".
The sending off of Mark Noble at the King Power Stadium on Saturday evening was bad news for West Ham, whose squad is looking increasingly thin, but it could open the door to Conor Coventry.
Pellegrini added: "I trust in him because for me one of the most important thing for me as a player is that when you have the ball, you give the ball to a player in the same colour shirt".
"I am happy with the performance and the way the team played but not with the result." the Chilean told the BBC. We started very well, but after, I don't know why, we lost control. He is playing well and was at his best in this game, so it is hard.
The helicopter belonged to chairman Vichai Srivaddhanaprabha, who bought the club in August 2010 and was named chairman in February 2011 before overseeing Leicester's Premier League triumph in 2016.
