He insists he is where he is now because of the Royals manager's faith in him.
Long told the WBA website: "When he got the job, I was struggling, I wasn't playing well, but he stuck by me and I managed to score nine or ten goals at the end of that season.
"At the start of the following season, I scored one in 13 and he still stuck by me, but I finished with 25 in total.
"He gave me his spare room for two months and he took me under his wing for a while.
"I was cutting his lawn and he really looked after me, took me to training and whenever I needed some help, he was there for me.
"I owe him everything and I'll be forever grateful for that."
