Hard to answer. I find it difficult to blame the poor performances of a team solely on their coach. At the end of the day the players have to deliver on the pitch and of course the coach takes the most responsibilites, thats just how football works these times but I do think his dismissal is justified here. There haven‘t played a good game this season yet and RB is a club with high ambitions so at this point they just have to pull the plug. They can‘t afford loosing this much points this early in the season. But coming back to my initial point, I do think that coaches get fired a bit too quickly nowadays especially in the premier league. A prominent example of this season is for me the release of Scott Parker at Bournemouth. He won against Villa and Norwich and only lost to Arsenal, City and Liverpool and got sacked. It is completely normal to lose those games and to sack someone for losing against those teams is just really ridiculous.
