From 1 January, Premier League games will start on the Monday before Christmas, with the final scheduled to kick-off on Boxing Day.
There will be two rounds of fixtures in the first two weeks of the season.
It will then kick-start in the new year with the first three weeks played in January.
What are the changes?
The schedule will be split into four groups of six games each, with a first-leg tie the second leg.
The teams in each group will then meet in the semi-finals and the winners will face each other in the final.
This is where the two-legged knockout will take place.
The sides will then play the final at the end of January, with all of the teams facing each other again.
What will happen on the pitch?
The two-leg knockout will be played in the same venues as the knockout stages, but will take places at the same time, with an extra-time format.
In the first leg, teams will play a total of 14 minutes of football.
There are two goals scored in each game, with teams getting a goal when a player has crossed the ball into the box or a penalty when a shot is blocked.
In total, there will be 34 shots on target in the two legs.
There is no extra-Time format to the knockout, with two goals scoring in each round and two goals coming from penalties.
Can I watch it online?
The Premier League will broadcast the knockout rounds live on Sky Sports and BT Sport, with BT Sport’s Sky Sport 1 being the official broadcast partner.
In addition, BT Sport will carry live coverage of the second round, with live games across the weekend.
It is expected that the knockout round will feature live kick-offs.
