Liverpool will hope to regain their spot atop the Premier League table. Despite being relegation-threatened Southampton aren't any boys to beat so tough battle is expected.
Virgil Van Dijk is a doubt to face his former club. But, Jurgen Klopp stated in his pre-match conference that the Dutchman is fit and raring to go to St. Mary’s.
Since the injury of Jojo Gomez and the entry of Matip, for some reason Van Dijk get less into the certain games. He prefers to stay a little behind and let Matop get the ball, and receive more balls than him. There's nothing more to compare the statistics between the two in the last few games.
I do not see reason to seek extension of average 80 passes per game for Dutch player. Last run expose downgrade of his performance in away matches (131 vs Brighton, 88 vs West Ham, 63 vs Everton and 67 vs Fulham).
