Every team involved in the UEFA Champions League Group Stage has had the chance to play their first game, and with some footballers already enjoying success from Day One, fans will surely be wanting more in the next few weeks.

Real Madrid had an easy match against Cyprus' top-ranked team APOEL, while Tottenham earned themselves a 3-1 win over Borussia Dortmund. In The Netherlands, Manchester City carried on with their fine display on both sides of the pitch by thrashing Feyenoord, but it wasn't all sunshine & rainbows for English teams, as Liverpool wasn't able to walk out of Anfield with a win after drawing 2-2 against Sevilla.

Let's have a look at some interesting facts following the conclusion of Matchday 1 in Europe's most competitive club competition.

Aubameyang handed massive blow with disallowed goal

Things could have gone differently for Borussia Dortmund if Italian officers working at Wembley had allowed a clearly valid goal for Pierre-Emerick Aubameyang. Moments after the Gabonese ace saw his name taken down from the scoreboard, Harry Kane scored Tottenham's third goal of the day. Did anyone say "VAR"?

Lucky for Spurs....Aubameyang (top of picture) was well onside.... Should've been 2-2, now 3-1 to #THFC pic.twitter.com/L87YOik3m1
