West Ham United boss David Moyes admits he was disappointed with the lack of quality his side produced during their 1-0 Carabao Cup defeat at Arsenal.

The Hammers travelled to the Emirates with high hopes after a good run of games which has seen them unbeaten in their last 3 without conceding a single goal, but they failed to match Arsenal’s superiority during the game.

Danny Welbeck scored the game’s only goal to condemn the Hammers to defeat, and Moyes admitted his frustrations towards the Hammers, but said he remains focused on the Premier League.

Speaking on West Ham’s official website, Moyes said: “We tried to do all the right things and play with determination and shape, but what we lacked was quality but I have got to say we kept at it.

“We have played Arsenal in two games recently and lost one goal, and that was as bad as you can get in the way we conceded it. It wasn’t what you would say was an Arsenal goal and maybe we could have defended it better.

“It was really poor, we should have done better with the first ball in and I’m hoping that one of the centre-backs clears it out when the header comes across.

“We have been defending well recently so I wasn’t expecting it, that’s for sure. Tonight we didn’t play well enough but we were never out the game.

“I think when you get to this stage of a competition when you’re West Ham, you would [like to field your strongest team]. But you look at Arsenal tonight, with a game on Friday, they changed their whole team.

“With our league position, on another day I may have done the same. Undoubtedly the Premier League is where you have to be. Everyone wants to win a cup, I’d love to, but ultimately all the talking at the end of the season will be about the Premier League.

“I think we have been making progress and winning games and we’ve been well organised and hard to play against. We showed that again tonight.

“But what we’re seeing as we go along is the next step is adding quality. Tonight we were short on midfield players and generally we’re short in that area and we could do with adding a little more craft.

“It’s an area we’re short at the moment. But January is never the easiest month to deal with. It was great young Dom played well and Declan Rice got a good game, so we have to develop our own players too.

“But we just lacked a bit of quality tonight at different times.”
