Liverpool manager Jurgen Klopp said that his side must improve their commitment levels if they are to make progress this season following a 2-0 defeat at West Ham United. Klopp has identified this month's games as crucial to Liverpool's campaign, with a League cup semi-final against Stoke City and an FA Cup trip to Exeter City while there are also potentially tough league meetings with Arsenal and Manchester United.

And he has demanded immediate improvements after seeing his side undone by headed goals from Michail Antonio and former Liverpool striker Andy Carroll at Upton Park on Saturday.

"It's no day for being disappointed, it's a day for being angry," said the German, who has now overseen four Premier League defeats in his fledgling Liverpool tenure.

"We had the ball and possession and bad luck in a few situations, but that's not what I want to see, to be honest. You have to be there in the decisive moments.

"If you fight in these moments, but at 100 percent -- 95 percent is not enough. Who wants to see 95 percent? -- that's what we have to do. West Ham completed a first league double over Liverpool in over 50 years and manager Slaven Bilic singled out Carroll for praise afterwards. "Andy was brilliant, not just because of the goal, but for his performance, everything: defending, holding the ball up," said the Croatian.
