European champions Liverpool will have to do without the services of captain Jordan Henderson for three weeks’ manager Jurgen Klopp has confirmed.
Henderson sustained the problem in Liverpool's Champions League last-16 first-leg defeat to Atletico Madrid in midweek.
Speaking on his press conference on Friday, Klopp said: "It could have been worse. We all know it was a hamstring thing.
"There are a lot of different hamstring injuries around in the Premier League - Harry Kane, for example, stuff like that. It's not that bad. He will be out for three weeks or so, which is not cool. But how we see it is that we're lucky."
The injury means that the England midfielder might miss the second leg between his side and Atleti though the team has favourable-looking league fixtures coming up against. They start with West Ham on Monday, Watford and Bournemouth, although they also play Chelsea in the FA Cup and visit Merseyside rivals Everton immediately after the Atletico game.
Liverpool has a 22-point lead at the top of the league with just 12 games remaining but Klopp suggested he was not looking to rest players against West Ham in order to prevent further injuries.
