Kyle Walker's performance would have been the source of encouragement for someone waiting in the wings.
No one likes to watch their side lose.
But it's a little different for a footballer sometimes - especially one that's competing to break into a starting XI.
The 21-year-old would have been watching his side lose 2-1 at Crystal Palace yesterday and he - like his team-mates - would have been discouraged that the north London club's unbeaten run had been brought to an abrupt halt.
When it comes to his first-team chances, however, Yedlin might just have been watching with glee as Kyle Walker struggled to deal with Crystal Palace's Wilfried Zaha - especially for the Eagles' second goal.
Walker has impressed since returning to fitness for Tottenham but, defensively, he is yet to fully convince. Yesterday, meanwhile, the right-back took a big step in the wrong direction in that respect.
What a boost, paradoxically, for Yedlin. The 21-year-old, primarily a right-back, would have been looking at Walker and thinking 'this is beatable competition.'
For, if the Tottenham defender continues to produce shaky displays like yesterday's against Crystal Palace, there will be only one beneficiary - his biggest rival for a starting berth.
