To be fair to Ben Foster, he might have had other things on his mind.
Anyone else waking up to the fact that their @OfficialFPL season is ruined because they forgot that the game week started last night 😔— Ben Foster (@BenFoster) April 6, 2019
But then he and his Watford team-mates did have an FA Cup semi-final against Wolverhampton Wanderers on Sunday to prepare for, which the Hornets won 3-2 after extra-time.
So, for Ben, and for the many other FPL managers out there afraid of missing future deadlines (and beware, there are more Friday ones on the way), here are the dates and times you need to know for the run-in.
Of course, the easiest way not to forget is to get notified of the impending deadlines by the Premier League app.
You can do this very easily by going to the "More" section of the iOS or Android apps.
There you will see the "Notifications" section.
Scroll down to the Fantasy notifications and switch on "Gameweek Deadline".
Remember also to allow notifications by the app in your device's notification settings.
