It was the England international defender’s own goal that proved to be the difference between the two sides at Old Trafford in the Premier League clash.
The unfortunate incident happened midway through the first half, and the 25-year-old right-back has given his thoughts on it.
“We gave them a game today but we just lacked the goals,” Walker told BBC Sport.
“(For the own goal) I tried to stick my foot in the way so that he’d kick my foot instead of the ball, so it’s a bit unlucky really as I’d made up a lot of ground to get there. We just look onwards and upwards to our next game.”
Despite the defeat, Tottenham did play relatively well and gave a good account of themselves at Old Trafford.
Over the course of the 90 minutes, the North London outfit had 50% of the possession, took nine shots of which four were on target, and earned two corners.
It is a disappointing start to the 2015-16 Premier League campaign for Spurs, but they should remain optimistic about the season ahead.
After all, winning against United at Old Trafford is not easy and a point would have been a bonus.
