I know it's tough to properly compare club teams across multiple European leagues, but according to ESPN 538 (

Fulham is currently ranked as the 65th club in the world.
Anderlecht is currently 178th
I'm just going to have to disagree with you that being in the team of the season for the Belgian league is all that impressive.
Pep and the board saw something in him though, so hopefully he comes good.
I was excited for his second half of the season, because I thought a month off from playing and just training would help get him caught up to speed, but then he had one of the worst performances I've seen in awhile vs Southampton from a City player.
