He deserved it - he got too many chances to turn the season around but failed, no way anyone was retaining their job after the season he had. Winning a lucky Europa league doesn't change anything. The worst they have had in the last 10 years.
Even he deserved the sack that is actually painful for him, his experience with Tottenham Hotspur is very memorable and changed his coach career. There are not many coaches who managed to win UEFA Europa League titles and Postecoglou is one of coach winners in Europa League in history.
His adventure with Tottenham Hotspur is like a mix of sweet and bitter experience that starts with a very first promising season in which sometimes he and Tottenham Hotspur saw opportunities of competiting for Premier League title; and a last season is a completely failure in Premeir League while they won Europa League title surprisingly.
I don't trust players coming from Bayer and Leipzig Kai Havertz, Nkunku and Timo Werner taught me a lot.
This young man is different and he is truly talented and show his ability in Liverpool and Premier League. I don't consider Havertz, Nkunku and Werner as players who have as same quality as Wirtz.
