Jurgen Klopp admits he is concerned that Sadio Mane has suffered a recurrence of his hamstring injury.
The 25-year-old has been sidelined for a month due to the problem but made his return in the 4-1 win over West Ham on November 4.
Mane helped guide Senegal to next year’s World Cup by playing the full 90 minutes in their 2-0 win over South Africa on Friday.
Senegal are due to play South Africa again on Tuesday but Mane has been sent back to Liverpool due to his hamstring injury and will undergo tests to find out the extent of the damage.
‘Specifically on him returning to Melwood early to be with us; obviously it is a concern that the hamstring injury is again on the agenda and it will be critical for us to monitor and manage that in the coming days,’ Klopp told Liverpool’s official website.
‘At this stage we haven’t seen Sadio yet to properly assess the extent, but what is clear is that we will have to stay on top of this for the rest of the week and make sure we are careful in how we look after him.
‘There has been really strong communication between ourselves and the Senegal team management to ensure the player is properly protected and looked after.
‘We respect how important he is for Senegal and therefore it must always be the case that they get to make the decision when he is under their care.
‘It should not be forgotten in Liverpool, either, how important it is to Sadio that he represents his country whenever he is fit enough to do so.
‘He is so proud of his country and recognises what a role model he is for them.
‘So, in this moment all I can really say with certainty is that we will assess Sadio as soon as he lands back in the country and make decisions on what rehab and treatment gives him the best chance of being back fit and strong for the important fixtures we have coming.’
