Liverpool manager Jurgen Klopp has expressed his concerns as Sadio Mane and other squad players prepare to head off to international break.
However, the worry surrounds Sadio Mane more than anyone - as the Senegalese forward returned to action against West Ham in a 4-1 win. Sidelined for just over three weeks with a hamstring problem, his return has been miraculous as Mane only missed five Liverpool games.
As quoted by the Daily Star, Klopp said: “I have no problems with international games, I'm really happy for Senegal that they could go to the World Cup and they need Sadio Mane for this, I understand, he is fit to play.
“I am always worried, to be honest. It is the most difficult time for me. [Injuries] can happen every day; it can happen in our training, in their training, it can happen in a game, but that’s how it is."
The Reds have suffered injuries to numerous first team players so far this year, with Adam Lallana, Nathaniel Clyne, Jordan Henderson and Philippe Coutinho all currently on the treatment table.
Liverpool have suffered during the spells that Mane is absent - notably around Christmas time during the African Cup of Nations and following a knee injury sustained in April of this year. Having said that, the addition of Mohamed Salah has made them much more prepared for the potential loss of Mane.
“The only thing I would ask is if they can make it in the first game then it would be cool if he could come back and could make the preparations for our game against Southampton" said Klopp, "I cannot decide things like this, I don't even try, but we are in contact."
With Senegal set to play South Africa next Friday, a win would secure qualification from their group. However, if things don't go according to plan in this match, the sides play each other again just four days later - which may highlight the reason behind Klopp's worries.
