David Moyes was sent off in extraordinary circumstances as West Ham lost to Frankfurt in the Europa League semi-final.

West Ham lost 1-0 in Germany after having Aaron Creswell dismissed after just 19 minutes. Seven minutes later, the Hammers trailed their German opponents 3-1 on aggregate after Ansgar Knauff gave the home side the lead on the night.

From that moment onwards, West Ham faced an uphill challenge. To their credit, they went out fighting but just couldn't find a way through to give themselves hope.

And as the minutes ticked on, frustrations started to get the better of them.

And Moyes demonstrated those frustrations as he reacted badly to a ball boy not giving the ball back as quickly as he would have liked.

The young ball boy dropped the ball towards the pitch - rather than throw it - and Moyes retaliated by kicking it back in his direction.

He was deservedly shown a red card by the referee, Jesus Gil Manzano.

Now, new footage has emerged of the incident that earned Moyes a red card, clearly showing his intentions of kicking the ball at the boy.

After the match, Moyes did apologise for his actions but didn't appear to be too sorry.

"I have to apologise for kicking the ball," Moyes said. "The ball boy left it short nicely on the volley for me. I apologise for it.

"It didn't hit him, I think I bent it past him."

While 10-man West Ham were defeated 1-0 on the night, Moyes believes the tie was actually lost last week in east London.

"Let's be honest, we probably lost the game in the first few seconds at London Stadium when we conceded," Moyes said.

"We were chasing the game since.

"I am really proud of the players. How they played with 10 men was fantastic. They stayed in it. Other teams would have folded and lost two or three.

"I thought we had better chances than Frankfurt. But we congratulate them. They go through, we don't and we give them our best wishes."

While he may give them his 'best wishes' Moyes admitted he wasn't impressed with the reaction of their bench during Creswell's sending off - which was upgraded to a red from a yellow by VAR.

"I thought it wasn't great officiating throughout. Aaron has given the referee a decision to make. I was more disappointed with the Frankfurt bench. The whole bench came out, it comes back to haunt you," he said.

"I hope our bench wouldn't react like that. Maybe we should change how we do it, we do it by Queensbury rules."
