Sadio Mane had an ally in Lionel Messi after being 'left with a bitter taste' by Jurgen Klopp's decision to back Virgil van Dijk for last year's Ballon d'Or.
According to France Football, the Senegel star was unhappy that his manager publicly called for Van Dijk to win the prestigious award.
The Dutchman eventually finished second to Messi in the standings, while Mane came fourth behind Juventus star Cristiano Ronaldo.
The former Southampton winger excelled in the 2018-19 season with 26 goals to propel Liverpool towards a sixth Champions League success and almost the Premier League title.
