Tottenham Hotspur get their pre-season friendlies under way by taking on Juventus in Singapore's national stadium.
The game is part of the International Champions Cup, a friendly tournament played across North America, Asia and Europe and involving some of the sport's top sides.
Mauricio Pochettino's side take on Juventus first before heading to Shanghai to play Manchester United and then they will welcome Inter Milan to the Tottenham Hotspur Stadium next month.
Friendlies can often having all different kinds of rules and the International Champions Cup has very specific ones when it comes to substitutes and even penalty shoot-outs.
Here are the basics:
Match length
That's still the same, it's the regular 90 minutes until the final whistle, however.....
What if it's a draw?
If the teams can't be separated at the end of the 90 minutes, the match will be decided by a penalty kick shoot-out.
How many players can be named on the teamsheet?
Thirty players may be included on the team sheet, with the 11 selected starters and up to 19 players on the bench.
How many substitutes can be made?
Each team can make 11 substitutions, although, at the discretion of the referee, a 12th substitute may be allowed.
When can substitutions be made?
Due to the number of substitutes who can be used, rather than fragment the match too much, substitutions are only allowed a maximum of three times during the match. Substitutions made at half-time will be counted against those three allowed opportunities.
However, any player deemed as injured by the referee may be replaced and his replacement shall not be counted against the three permitted substitutions.
How do the points work afterwards?
The teams get three points for a win, two points for a penalty kick shootout win, one point for a penalty kick shootout defeat and no points for a loss.
