The Reds were heavily linked with a move to sign the Netherlands international from Southampton earlier this summer but a deal failed to materialise.
Indeed, Liverpool were forced to issue an embarrassing statement apologising to the Saints about a “misunderstanding” surrounding their pursuit of the Dutch star.
However, the Reds continue to be linked with a move to sign the 25-year-old, who is thought to be keen on working with Liverpool boss Jurgen Klopp.
The Merseyside outfit have also been touted with making a club-record bid to sign RB Leipzig star Keita in the current transfer window.
The 22-year-old Guinea international was one of the Bundesliga’s standout players last season following his £12.75m switch to RB Leipzig from Austrian side Red Bull Salzburg.
Speaking to ESPN FC on Monday about the possibility of Liverpool signing Keita or Van Dijk this summer, Nicol said:
“I think there is a good possibility both might happen [Van Dijk and Keita signing for Liverpool].”
Liverpool signed former Chelsea winger Mohamed Salah in a £36.7m deal from Serie A giants AS Roma earlier this month.
England Under-20 international Dominic Solanke has also completed a free transfer to Liverpool from Chelsea.
