He said:"He's definitely coming in here and I guarantee he is sitting there amazed. 'Like what is this? This isn't what I expected to come back into.' I reckon Ten Hag is walking in thinking, 'I didn’t know it was this bad.' Is it irretrievable?"He added:"Does it need an absolute mass turnover where all you aren't good enough and we’ll get rid of all of you? You can’t do that. I think that’s the dream scenario. If Erik ten Hag could say: 'I'll get rid of all these players and start with another 11' - he would. I think he actually would."
