The teenage winger made his debut in the 2-0 defeat to Scunthorpe before coming off the bench to score in the 4-1 thrashing at Derby this Saturday.
So impressive was Whichelow, his teammates have lavished him with praise in the media this week, including centre half Martin Taylor who believes the youngster’s goal at Pride Park can only be a good thing.
"There's nothing better than when you get your opportunity to get your name on the score sheet, then people start asking 'who's he?’” Taylor said.
"He got in some great areas, it was a great finish and I'm made up for the lad because he's worked hard in training.”
Even manager Malky Mackay took time out to praise Whichelow, suggesting the youngster could be the ‘future of Watford’.
Born in Islington, Whichelow rose through the Academy with high-rated duo Eddie Oshodi and Piero Mingoia. Lee Hodson, another colleague, has already made 41 first-team appearances in just two years.
Twenty one goals for the academy last season, including a 32-minute hat-trick against Stevenage Borough in April, underlines Whichelow’s goalscoring ability, a very useful trait for a midfielder. He also bagged two goals for the reserve side.
A recent investigation looking into the average age of Championship squads revealed that Watford had the youngest by some distance at just 21 years and 21 days.
And with the team sitting in ninth spot in the Championship, above big-spenders Sheffield United, Nottingham Forest and Middlesbrough, it proves that money is not everything in this division.
