Was speaking to my Forest supporting neighbour towards the end of last season.
My prediction to him was Kane goes to Utd, then we bring in players from relegated clubs, namely Maddison, Bamford and Ward-Prowse if he doesn't replace Rice at West Ham.
I suggested Forest would stay up otherwise we would bring in Johnson, which genuinely annoyed him. I certainly haven't studied his play, but he was basically saying he knows they won't be able to hold onto him, but another couple of years would do him good etc. He was gutted to hear there were even ideas of him leaving, which was enough for me to think - probably worth a punt then.
When fans that watch every game don't want a player to leave, it's usually a good sign. So I'm all for Johnson even though I have probably seen him play fewer than 600 minutes personally.
