Jurgen Klopp has congratulated Sadio Mane on his national sides success in reaching next years World Cup finals but will monitor him closely with rumours of a potential injury.
Senegal released the player back to Liverpool - ahead of their Tuesday game against South Africa saying the player was 'feeling his previous hamstring injury'.
The Liverpool player had only made his return to the LFC squad the day before he jetted off for international duty - when he played in the 4-1 victory over West Ham.
He missed 3 weeks, and five games, action for the reds after his initial hamstring injury and Klopp had been questioning about how Senegal were planning on using the attacker, in both matches and training. Communication was eventually established between Liverpool and Senegal about how to manage his continued return to fitness.
The reds face Southampton on Saturday at Anfield and the Liverpool boss told the official website:
First and foremost, I have to say big congratulations to Senegal on the achievement of qualifying for the World Cup; this is fantastic news for their country and the players - Sadio included.
Turning to news of a possible injury, Jurgen added:
"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.
“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.
Sadio Mane has 3 goals and 4 assists to his name in his 10 LFC appearances so far this season.
The reds face Southampton in the Premier League on Saturday at Anfield as the busy winter schedule gets underway.
