West Ham United stifled Chelsea into submission as the Hammers got their first three points under new boss David Moyes.
Midfielder Manuel Lanzini reckons that Moyes outthought his west London counterpart Antonio Conte, inflicting a fourth defeat on the champions, that leaves their title defence in tatters.
Lanzini said to the BBC: of the 1-0 win, a goal he set up in the seventh minute for striker marko Arnautovic: “We really needed the win, especially given our situation in the table. We knew that it was going to be an extremely hard match but we had the right system, like we did against City, where we could also have got a point, but this time luckily everything clicked.
"We played great in defence and we converted the chance we had, which was really important and we played a great match.
"Obviously we know the situation we’re in, and we need to win. It’s essential to us. Every match is a final from now on and we need to play every match like today.
"We won against one of the best teams in the league and we hope we can play like that for the rest of the season.”
