There were others who blamed him for them going down but it seemed like a very vocal minority imo.
Of course they would.
Everton were partly responsible for ruining their 2017-18 season (Silva fiasco).
Then we took the most promising attacking midfielder they've ever had in Richarlison.
Now we are taking their best defensive midfielder they've ever had (who they wrongly played further upfield).
They're naturally going to despise Everton. And I don't blame them. We collectively despised Man City for a few years after they took Lescott and ruined one of our seasons. But them being southerners, I'm sure their grudge will last decades.
Richarlison scored a goal every 8 games for Watford. In a very poor Watford side. A lot of Watford fans were saying how overated he was when he was going to us. Yet, he comes to one of the poorest Everton teams in over a decade and scores a goal every 2.7 games.
Doucoure will naturally play better with better players around him if he comes to us. I'm confident that we will only improve. Plus he will be used right as he now (and we) have a proper manager who actually plays players in their correct position.
