West Ham United boss David Moyes will take charge of the London side for the first time against Watford.
There are some fears that Moyes’ usual brand of football will not satisfy the London Stadium crowd, who demand to be entertained.
But Redknapp argues that Moyes should stick to his guns and keep Carroll in the team.
The experienced boss, who is currently out of work, believes that West Ham’s performance came against Huddersfield Town.
On that day, the Hammers won 2-0, with Carroll leading the line.
And Redknapp believes that performance should have shown Moyes how he needs to play at the London Stadium.
“The best I’ve seen West Ham play this season was the Huddersfield game at home,” Redknapp said.
“Andy Carroll play and they handed it to him at every opportunity, when they got in the final third. He dropped it down, the little guy Hernandez was lively and running off him and getting around him, and if that’s effective then that’s the way you’ve got to play.
“If I was there now I’d have to be honest, you’d get that style.”
Moyes’ appointment at West Ham has not gone down well, but the Scot is under pressure to get things right quickly.
The Hammers are currently in danger of relegation, and sit in 18th place in the Premier League table.
Moyes will take charge of his first West Ham match in two weekends’ time, when his new side take on Watford at Vicarage Road.
