With nine goals, deep-lying playmaker Steven Gerrard finished as the Reds' top goalscorer in the Premier League last season.
Consequently, a talisman is said to be high on the list of priorities at Anfield this summer and speculation has mounted that Benteke heads the shortlist, with Rodgers reportedly bidding an improved £25m last week.
"The striker issue is a big thing," Fowler, who netted 183 goals for the club, told the Liverpool Echo. "We didn't have anyone who scored 10 Premier League goals last year and I can't remember the last time that happened at Liverpool.
"It's important we get a proven goalscorer and, of the names being bandied about, I'd go for Benteke. I think he's excellent.
"I know there are other top strikers out there and probably more prolific scorers but in terms of all-round play - strength, speed, physicality, finishing - I think Benteke could be the main man for Liverpool. I think we cross more balls into the box than any club in the league and I think Christian says he feeds off crosses. There's no point going to a club where they don't cross the ball."
Earlier this week it was reported that the 24-year-old Belgian would snub a move to Tottenham Hotspur in favour of joining the Merseyside club.
