The former Arsenal youngster may feature at the Emirates Stadium on Saturday, with first-choice winger Aaron Lennon facing a spell on the sidelines with an ankle injury.

Bentley has been disappointing in a Spurs shirt since joining the club from Blackburn Rovers in summer 2008, but caught the eye in the Carling Cup win over Everton on Tuesday.

"Plenty of questions have been asked about Bentley but he gave some of the answers against Everton and I'm hoping there will be more answers in the North London derby at Arsenal," Redknapp said. "His performance was worth its weight in gold.

"What Tottenham need now is more of the same from Bentley and I can't think of a better place for him to do it than at one of his former clubs.

"It's not been easy for David of late. By his own admission, he's not been pushing Aaron Lennon hard enough for the right-wing position - until Tuesday night that is.

"A lot of people also have completely the wrong idea of what he is like to deal with. I can tell you he is a decent lad.

"Sure he's a good-looking young man and has talent in shedloads but he is not the flash Herbert some try to make him out to be.

"Not so long ago, he was being tipped as David Beckham's successor on the right wing for England but now young Lennon is in possession of that place.

"What my team will need at the Emirates is Bentley supplying plenty of those quality crosses to put the Arsenal defence under pressure."

Bentley's only Barclays Premier League goal for Tottenham last season came at the Emirates Stadium in a 4-4 draw. The 25-year-old scored with an amazing 43-yard dipping volley in the first-half of that match.
