With Terry injured, Gerrard is the favourite to win the armband for next week's friendly against Switzerland for Fabio Capello's first game in charge.
"The bottom line is that Steven Gerrard doesn't need to be England captain, but you get an extra 10 per cent from JT if he's in charge," he told the News of the World.
"I'm not saying John is less of a player when he's not captain but, since he was a kid, he's been used to being a leader on the pitch.
"Stevie is similar to (David) Beckham in that he leads by what he does on the pitch.
"You think back to what Becks did against Greece in the last 20 minute of the World Cup qualifier in 2001, which culminated in his free-kick goal which took us to the Far East.
"Then you compare that to Stevie's performance away against Andorra last March in a Euro 2008 qualifier. Both those displays were very similar. They lifted the team by taking the game by the scruff of the neck.
"John is totally different. He gives orders, he organises people and he'll put his body on the line every time."
