Tottenham Hotspur boasted a record home attendance on Wednesday night (September 14) in their UEFA Champions League group stage opener against Monaco - but they weren't actually playing at home at all.
This is because Spurs will be playing all European home fixtures at Wembley Stadium in west London this year, while construction work is carried out to build a new 61,000-seater stadium next to White Hart Lane.
Our Spurs fan reporter who was at the game last night - which Spurs lost 2-1 - has written this handy explainer for those still puzzled about why this is happening .
But one glance at Twitter last night is all it takes to see that the move has left many fans puzzled, even as the game was being played.
Here's what the spurs boss had to say after the game - at WEMBLEY
Even some accounts covering the game had stated it was being played at White Hart Lane up in north London.
Don't forget that all of Tottenham's home Champions League games will be at Wembley, so make sure to head to the right place for the Bayer Leverkusen game on November 2 and the CSKA Moscow clash on December 7.
So, with confusion rife, it begs the question of whether some fans with tickets came a cropper and headed to the Lane mistakenly expecting a game to be on.
Here's the best of the confusion from Twitter last night.
We agree with Jack, there must be SOMEONE out there, surely!
It doesn't look like Alan went to the game, but he was still bamboozled by it being played at Wembley
Could Russell be our first culprit? Probably just joking. But is he though? Probably.
This is about as close as we're going to get to evidence. Hopefully this lady wasn't talking about last night's game...
So, okay, most people tweeting about mistakenly thinking the game was at White Hart Lane were obviously joking.
But chances are someone, somewhere (maybe a Monaco fan?) turned up at White Hart Lane last night. And if they did, then they probably wouldn't advertise it on Twitter.
Our search goes on.
