What happened to Liverpool fc Mane’s goals this season?

The senegal international was finding the back of net consistently last season however it isn’t the same story this time around There was goodish excitement when Sadio Mane signed for liverpool in a then-African transfer record deal of £34 million within the summer of 2016 from Southampton, but ahead of a match against his former club, is that the African nation international at risk of losing his way?
After scoring a superb brace once the Saints beat the Reds 3-2 in March that year, it absolutely was a significant boost for Jurgen Klopp's side once the attacker proceeded to replicate this level of performance on a daily basis.
Mane boosted his reputation as he scored thirteen goals during the 2016-17 season and made the PFA Team of the Year, though his season was partially cut short by participating within the 2017 African Cup of nations for senegal and also missing the last 2 months of the campaign with a knee injury.
