Theo Walcott has become the club’s number one striker in recent matches.
Walcott has currently won over boss Arsene Wenger and begun the last few matches as the team’s leading striker, a position usually taken up by France international Olivier Giroud.
It comes after the former Southampton star’s pleas to play in his favoured role, having featured numerous times in wider areas with Wenger looking to make good use of his pace.
Speaking to Sky Sports, Redknapp also shared his belief that Walcott is more suited to a wide role but admits he has been taken aback by the forward’s form in the number nine position.
"Theo Walcott has surprised me. I've said in this column before that I think he's a better wide man but he's been brilliant in that role. He's been electric. When he's on form like that, he gives you a different dimension," Redknapp explained.
"Walcott is certainly one of the catalysts for Arsenal. I like Olivier Giroud - he's a good, honest player - but Theo has that blistering pace and Watford's defence will be scared stiff of that on Saturday."
Redknapp has hit the nail on the head with regards to Walcott giving Arsenal a different dimension through the middle, because his pace and movement can stretch teams.
The 26-year-old caused Manchester United all sorts of problems in the recent 3-0 win at the Emirates yet one has to consider how much space he was afforded by a naive opposition.
Walcott is superb at exploiting the space in behind a defence playing a high line but question marks remain over his impact against a side who drop deep and look to counter.
It’s well documented how Walcott rarely mixes in with build-up play and against a deep defence is where a target man in the mould of Giroud helps get the attacking midfielders more involved.
The Gunners are fortunate to be able to alternate their strikers, as both players have the ability to play a key role for the team depending on how Arsenal's opposition set up.
