Liverpool's niggling injury problem during their tour of the United States continued with Divock Origi missing the game against AS Roma on Monday (1 August) due to a minor groin injury, while Alberto Moreno suffered a dead leg which saw him limp off midway through the clash against the Serie A side, which they lost 2-1. Jurgen Klopp has allayed fears of a serious injury to his defender, but will be concerned with the number of players suffering minor knocks since the start of pre-season.

"Yes, [he is OK] – dead leg in the hamstring. He couldn't activate the muscle so you cannot play. That's how it is," Klopp said following the 2-1 loss to Roma, as quoted on Liverpool's official site.

The Liverpool Echo understands that the Belgian striker's knock is a minor one, but the Merseyside club did not want to risk aggravating it further. Origi has been impressive during their pre-season tour of the US and is likely to start for the Reds in their opening Premier League clash against Arsenal.

Apart from the duo, Klopp's first two Liverpool signings Marko Grujic and Joel Matip were also absent after failing to recover from concussion and a foot injury respectively. The former suffered his knock during the Anfield side's 1-0 loss to Chelsea on 29 July, while the latter has failed to play even one game thus far after suffering the injury during their pre-season friendly against Wigan Athletic on 17 July.

Meanwhile, Klopp has praised his players despite ending their US tour on a losing note, and believes his team has shown their true quality during some of their pre-season games, which bodes well for the upcoming season. Loris Karius is the only major injury concern for the manager after the German broke his hand during Liverpool's loss to Chelsea.

"The players have done really well on this tour. There have been a lot of perfect sessions and some really good moments in our games," Klopp said, as quoted by the Liverpool Echo.
