The FA refused to credit it to him, however, and he admits:
"I would hate to let it go," he admits, "but it was his first goal and he would want it, so I expect a phone call soon.
"But scoring against Ipswich was the same as last time we played them when I came on and scored, so it was good; the confidence was quite high and I enjoyed it.
"At 2-1 towards the end they were putting a bit of pressure on and playing a lot of long balls whereas normally they play good football.
"I was just delighted when I scored the third goal because it knocked them back and after that there wasn't long left.
"I remember getting the ball, Joe made a run, and I was going to slip him in but the defender followed him and his legs were wide open so I thought I might as well just shoot.
"I just laughed when it went in because I didn't really expect it to; it just bobbled, and it was a good feeling to see it go in was."
He smiled, too, when Paolo Di Canio carefully wrapped the captain's armband around him when he went off with three minutes to go.
"It was quite funny, deja vu," he says, "the same as last time, finishing the game with the captain's arm band."
He says the players can start looking up the table now, and adds:
"We have got good enough players to do play in Europe, international class players, and we'll have to see what happens between now and the end of the season."
As for full England ambitions, he says:
"If it is this year it is this year, if it's next it's next; I don't really think about it, because I'm still young and learning the game."
Glenn Roeder says that Jermain will "compete on a level playing field" next season rather than being always on the bench if the other strikers are fit, but he adds:
"Sometimes it gets frustrating but I can't really complain coming off the bench to score - and Fredi has battered them down before he came off."
Meanwhile, looking ahead to the Fulham game, Nigel Winterburn says:
"It will be a hard game; they are just below us, I suppose they need another win, but they will be confident that they can pick up enough points to keep away from the very bottom.
"It is exciting at the bottom and the top this year."
