The Egyptian global recovered in time to play for his country at the World Cup and has started all six of Liverpool's matches this season, but is yet to rediscover his record-breaking form of last season.
The England U21 star trained for the first time with his teammates after suffering the damage last time out, but Klopp says the game against The Saints has come too soon for him, adding: "Solanke trains for first time after concussion".
Last season Liverpool were more reliable for over 2.5 goals on the road and the early signs are that it might be a similar story this term, partly because most visiting teams have difficulty scoring at Anfield.
The Reds have enjoyed a dream start to the campaign as they extended their run to five consecutive victories in the Premier League with a 2-1 win at Tottenham Hotspur last weekend to remain joint top of the table alongside Chelsea.
Liverpool will be looking to maintain their ideal start to the new season when they welcome Southampton to Anfield on Saturday afternoon. It's really no problem.
