Speaking to Fulham's official website, John said: "I'd been waiting for a long time to be named in the starting XI for a League game.
"Lincoln was my first start this season and, naturally, I was getting frustrated at not playing.
"But Cookie talked to me and told me he still had faith in me and that I was an important player.
"And then when he told me I was starting against United I was so happy! I called my mum six times!
"She asked me to score for her and I did, which was a nice feeling."
