Versatile midfielder Gray became the youngest player to captain Tottenham in a competitive game, aged just 20 years and 163 days.
Unfortunately for him, Tottenham were unable to cap the occasion with a win, ultimately falling to a heavy 3-0 defeat to Keith Andrews’ impressive side.
Tottenham have spent close to £300 million throughout the summer transfer window in a bid to avoid a third successive relegation battle.
Speaking to Sky Sports after the game, a clearly disappointed Gray said: "For some reason on days in football, a team can outfight another team, it's on us and the fans have been incredible."
On fitness in the starting line-up: "I don't think there's any excuses to be honest."
On hangover from last season: "We've got work to do, you saw that performance. It's definitely an improvement from last season. It's not the start we wanted, going into the mid-week game on Wednesday."
On looking ahead for the rest of the season: "The work we do in the week is about moving in the right direction but today we got out-fought."
On becoming Tottenham's youngest-ever Premier League starting captain: "It was an amazing moment and I'm grateful for the manager for trusting me but again, today wasn't good enough."
