This happens in Cardiff quite often, also in the direction of the stadium. It seems to be caused by grow lights on the pitch which encourages the grass to grow faster.
If it is Spurs this could also be the case: https://www.tottenhamhotspur.com/news/2018/october/world-first-design-for-pitch-grow-lights-at-new-stadium/
Very characterful game, and quite fun too. I do worry about the replayability of it being a daily though.
