West Ham boss David Moyes insists the 3-0 scoreline flattered Manchester United.
United appeared comfortable winners on the day.
But Moyes said: "No I don't think the scoreline was correct. Our performance in the main was much better. I am pleased with that but obviously not pleased with different aspects, we didn't finish chances.
"Overall we played better and our performance was better today."
On Emerson Palmieri's miss to make it 1-1, he continued: "That tells you it just was not going to be our day. They broke away and they shoot and it takes a big deflection and that makes it 2-0.
"We have been on a pretty good run without being at our best, with some players also away. I thought today we looked like it but goals have been a little hard to come by. Hopefully there's a wee bit of mitigating circumstances and hopefully the goals will start flowing in the coming weeks."
On taking off goalkeeper Alphonse Areola at half-time, Moyes added: "It was just a case of we were making sure we were not doing the wrong thing. He is fine, we just felt there was no point risking him."
