As long as I know based on the current Jersey of Watford, Stake is still sponsoring Watford this season. You can check Watford official partners page https://www.watfordfc.com/club/partners or you can watch some highlight matches of Watford this season and you will see that Stake's logo is still printed on the jersey. It means that Stake is currently sponsoring both Everton and Watford. The best option is to add Everton in the title of this thread instead of remove Watford and replace it with Everton.
