The Reds have made a strong start to the new campaign under Jurgen Klopp and they have won all five of their opening games to leave them joint top of the Premier League table along with Chelsea FC.
Liverpool FC are aiming to challenge for the title this season after they finished in fourth place and without a trophy last term.
The Merseyside outfit reached the Champions League final last term but ended up falling short as they were beaten by Real Madrid in the final back in May.
Despite their positive form, Liverpool FC are still looking to win their first trophy under Klopp since his appointment back in October 2015.
However, Crooks seems to be convinced that the Reds will be Manchester City’s closest challengers for the Premier League title this season.
Writing in his column for BBC Sport, Crooks said: “At no stage did Tottenham’s back four come to terms with Liverpool’s front three.
“Every time Firmino picked up the ball, Sadio Mane and Mohamed Salah took off like stealth bombers leaving an airbase.
“Liverpool look like the team most likely to stop Manchester City from winning the title for a second consecutive season. However, should anything happen to Liverpool’s frontline attack then we may have a different situation entirely.”
Liverpool FC will kick off their Champions League campaign on Tuesday night when they host Paris Saint-Germain at Anfield in their group-stage opener.
The Reds reached the Champions League final but ended up as runners-up after their 3-1 loss to Real Madrid last term.
