I dont see it like that personally, and. i think he is as harsh on all the players imo, i think people just hear it different. After the game he was very critical of Rashford and Lingard, saying we looked even worse when they came on and also talked about how he was benched despite us missing 4 strikers that we started the season with.
People hear things differently, and for me it just feels as thought people cant wait to jump on him for saying what most fans are thinking. Its the same with Carragher and liverpool fans too.
