Arsene Wenger has been taking a stroll down memory lane by revealing the games he'd go back and re-visit with the help of FIFA's new VAR tool.
In case you'e not up to speed, the current Confederations Cup is currently underway with Video Assistant Referees in Russia, with several matches - including Portugal v Mexico - tangibly affected by the VAR's role.
There's a few incidents over Wenger's long and illustrious career that the Frenchman would love to have rectified and, top of the list, is the 2006 Champions League final.

Arsenal lost to Barcelona 2-1, and speaking via the Arsenal website, Wenger said: "I would choose Barcelona's equaliser in the 2006 Champions League final because it was offside, and we were 1-0 up with 30 minutes to go. That's the trophy I miss here, you know, so that is for me the most important one."

In fact, Wenger's second choice also involves Barcelona, and a knockout match back in 2011.

He went on: "The second one I would choose is the second yellow card for Robin van Persie at Barcelona in 2011, because this was the moment we were qualified against a very strong team, and it was a very difficult decision to accept - it basically killed our chances."

And Wenger's third and final choice is a little more recent, and reflects back to the most recent season gone, as Bayern Munich trounced Arsenal home and away.
The Gunners coach concluded: "After that maybe I go to a more recent decision - against Bayern Munich when the referee sent off Laurent Koscielny for a penalty when Lewandowski was offside.
"That just comes to my mind now but maybe I forget many, many, many, many more."

The hypothetical conundrum is a fascinating one, and makes us wonder what massive moments of footballing history might have been altered completely with VAR.
Maradona's handball? Geoff Hurst's goal against Germany in 1966?
Which matches would you like to go and re-visit? And are you glad VAR is now much more prominent in football?
