West Ham's dismal form in 2015 continued with a 3-0 defeat to Arsenal - and assistant manager Neil McDonald was fuming after the Hammers conceded a goal from a throw-in, telling the club's official website of his disappointment.
The Hammers had won just one of their last 11 Premier League games before travelling to face Arsenal at the Emirates Stadium - and that run become one win in 12 after a 3-0 thrashing.
Olivier Giroud opened the scoring on the stroke of half time with a rocket of a shot from just inside the box, before Aaron Ramsey and Mathieu Flamini added goals in the second half to wrap up the win for Arsene Wenger's side.
The defeat was another blow to manager Sam Allardyce's hopes of keeping his job beyond the end of the season, and he didn't even face the press after the game, instead sending assistant McDonald to answer questions from the media.
McDonald spoke to the West Ham official website at full time, and admitted that he was bitterly disappointed to have conceded the second goal, which came from a throw in.
"We were disappointed with their second goal, as it came from a throw-in situation and we work very hard on stopping the opposition scoring from set plays," said McDonald.
"The second goal killed us and didn’t really give us a chance to get back into the game, then their third one shouldn’t have happened because we should have shut up shop and not allowed it," he added.
The second goal was scored by Ramsey, and West Ham will be frustrated to have allowed Arsenal to get into the box so easily from a throw-in down the right hand side.
The throw-in was sent into Giroud, who dummied the ball to Ramsey, received a pass from the Welshman before returning the favour, allowing Ramsey to smash the ball home.
It was simple but effective from Arsenal, and West Ham - a team who pride themselves on work from set pieces at both ends of the pitch - will be rightly annoyed to have conceded the goal, even with the superb build-up from Giroud and Ramsey.
