Cascarino was speaking on talkSPORT about Henderson's time at Anfield from 2011 to the present day.
“Okay he might not have been as good as Steven Gerrard," Cascarino said. “Luis Suarez had his brilliance for a year – two years probably.
“And you've had some great players play for the club; Salah has been brilliant for two years, like Mane, and there are a huge amount of players.
“But if you're talking about 2010 to 2020, Jordan Henderson has done nine years there.
“And he has ended up being part of of that side under every manager.
“So I can't see how it can be anybody but Jordan Henderson."
