The Netherlands international moved to the Anfield outfit in a club record £75m deal from Southampton earlier in the January transfer window.
Liverpool FC made the 26-year-old the most expensive defender in the world after seeing off competition from Chelsea and Manchester City for his signature.
The Merseyside outfit breathed a sigh of relief when their big-money signing made the perfect start to his Liverpool FC career with a late winner in a 2-1 victory over Everton at Anfield in the FA Cup third round.
Liverpool FC are in fourth place in the Premier League table and three points clear of their closest challengers Tottenham Hotspur for a Champions League spot.
Former Reds captain Redknapp is confident that Van Dijk’s impact will ensure Liverpool FC win the race to claim fourth place.
“Everyone is vying for second place, but I think personally that by bringing in Van Dijk, you pretty much have cemented the top four with that one signing,” Redknapp told Sky Sports. “I do think he is going to make that big a difference.
“With [Philippe] Coutinho (leaving), there is an argument that might not have got you into the top four. As good as he is, defensively they have had a problem for a long time now and I think Van Dijk pretty much guarantees you top four.”
Liverpool FC will take on Portuguese giants FC Porto in the Champions League last 16 next month in pursuit of a first European crown since Rafael Benitez led the Reds to a famous triumph over AC Milan in Istanbul in 2005.
Klopp signed four players in the summer transfer window to bolster his Liverpool FC squad.
