It's the big final between Arsenal and Barcelona in the 2006 Champions League final at the Stade de France.
Instead of losing the final to the Blaugrana, the Gunners win it 1-0 as their goalkeeper Jens Lehmann is not sent off by the ref.
Arsenal win their first-ever UCL as do their great manager Arsene Wenger, who had never won European silverware in his storied career.
Arsenal don't have a trophy drought
After the move from Highbury to the brand new and state-of-the-art Emirates stadium, Arsenal do not have to let go of their top players like Thierry Henry, Cesc Fabregas and Robin van Persie in upcoming seasons.
They remain a top club in England and also in the Champions League.
The 8-2 against Manchester United, 6-0 against Chelsea, 10-2 on two legs against Bayern Munich never happens.
They also go on to win the league in 2008, 2014 and 2016 while maintaining respectability in Europe as a club to be feared from England.
#WengerOut never happens
The relationship between Wenger and the fans - a delicate one fueled by high-octane emotions - never deteriorates.
The trophies won, and the smooth move into the new stadium keeps Arsenal financially strong and fans never have to complain about paying too much for season tickets.
The fans never end up starting the #WengerOut movement as a call for change and improved results and he does not become the scapegoat for a failure by the board and the owners.
Wenger gets a fitting farewell for the hard work he has done and rightfully gets the respect he deserves from all the fans when he finally does call it a day.
