The Brentford loanee played together with the Stevenage star at Tottenham.
The 22-year-old is currently on loan at Brentford, where he is performing exceptionally well, as perhaps one of the best players in the Championship this season.
Of course, it does not always happened for youngsters at Spurs, no matter how talented they are.
Dean Parrett was snapped up from QPR in 2007 and went on to play four times for the club, all in the Europa League against the likes of Shakhtar Donetsk and Rubin Kazan.
But he was released in 2013 after an abrupt end to a loan spell at Swindon Town and went on to join Stevenage.
He was with Pritchard for a number of years at Tottenham. Pritchard joined from West Ham in 2009, so the pair played together for three years in the youth system at Spurs.
So yesterday Pritchard was happy to cheer on his former team-mate - who then went on to score a stunning strike in a 1-1 draw with Southend United in the League Two play-off semi-final first leg at the Lamex Stadium.
Pritchard will however hope to become a regular at Tottenham in the years to come. As for Parrett, it will forever be a case of what might have been.
