Jurgen Klopp insists he never doubted Mohamed Salah as the Egyptian ended an eight-game scoring drought to help fire Liverpool back to the top of the Premier League.Salah returned to scoring form with an outstanding solo run and finish as Liverpool recovered from falling a goal behind to beat Southampton 3-1 at St Mary’s and move two points clear of Manchester City.The title remains in City's hands, however, as the English champions have a game in hand.However, Liverpool remain five points clear of the bottom three and manager Ralph Hasenhuttl admitted his disappointment at his side's failure to hold on."If you take the lead after five minutes, you are going in the right direction," said Hasenhuttl."There is still a way to go but if you are a sportsman you are always frustrated if you are not winning. Not many have won against them this season, we had chances.”
