The Tottenham defender was starting his first game since being announced as Spurs captain.
Sunday's game against West Bromwich Albion was supposed to be an occasion to remember for Spurs defender Younes Kaboul.
Having recently been appointed the club's new captain, the French international would have been eager to lead his side to a comfortable three points against a side propping up the table leading up to the game.
Kaboul had skippered the side for much of this season, before Mauricio Pochettino officially appointed him his lieutenant on the pitch ahead of vice-captains Hugo Lloris and Emmanuel Adebayor.
But as it turned out, it was a day to forget for Spurs and their fans, as they crashed to a surprise 1-0 loss to the determined Midland outfit.
Speaking after the game, Kaboul was visibly disappointed as he offered up his thoughts on the affair:
"We all were disappointed after this poor defeat," said the 28-year-old.
"We played with a slow tempo all game. We never looked dangerous, or threatened West Brom. They took their chances and scored from a corner, and it was not good enough from us.
"I'm still questioning everything that went wrong today.
"We didn't create any chances and we were just inviting them to score and it's not good enough.
"But that's football, and tomorrow morning we have to come into training with a better mentality."
Kaboul looked ahead to the midweek League Cup game against Championship high flyers Nottingham Forest as an opportunity to make amends: "The game on Wednesday is important to us as we want to win something this season. We have to bounce back straight away."
