Pablo Zabaleta knows you cannot turn intensity on and off like a tap and that the Hammers need to be at it from minute one until ninety.
There were too many first half signs of what happens when that’s not the case at Brighton and Zaba has called for an improvement in the team’s mental approach.
He explained: “In the first half we gave the ball away often and cheaply. This is the Premier League and you can’t make those mistakes – we conceded the goal and then you always need to react.
“In the second half we were the better team, we kept the ball and created good chances but we couldn’t score.
“You need to be consistent as a team. Week in, week out you need to play well enough to pick up points. This is the most competitive and demanding league, so you have to be ready to play one game against a team who likes to keep possession, then the next against someone who is more direct.
“Every game is different and you have to be prepared to stop this. Then when we have the ball we need to play like we did in the second half.
“At this moment, all we need to do is learn and improve mentally, to be ready to play in the way we did for the second half for the 90 minutes.”
