The 22-year-old attacker is set play his final few games for the Bees in the Championship play-off semi-finals, having shone in the division with 12 goals in 45 appearances this season.
Pritchard, who will be given the chance to make the grade during Spurs’ pre-season, says the first leg against Middlesbrough on Friday night, live on Sky Sports 1HD, will be the biggest game of his career so far.
“My time at Brentford has been amazing,” he said. “The club has been great to me and it will be tough leaving, but that’s football.
“I’ve got on well with the lads and felt part of the team from the early stages. Hopefully there will be three more games, not just two, and I’ll enjoy them.
“Middlesbrough is going to be the biggest game of my career. It’s hard to switch off the big rewards but we are treating it as just another game. We have to perform against a great team.
“People had written us off before but we can’t wait for tonight. Training’s been good and the season starts now.”
Pritchard was named Brentford’s Players’ Player of the Year and earned a place in the Championship Team of the Year after impressing in a strong finish to the campaign.
“The awards have been massive to boost me on for next year,” he said.
“For the players to vote for me was great. Anyone could have won that award with their performances. To pick up as many awards as I have can only put me in good stead for next year.
“I think the defensive side of my game has matured here and hopefully I can kick on next season and play in the Premier League.”
