Statistics certainly seem to support the boss' thinking, Steffen has only started 12 games this season and has seven goals to his name - and he feels he should have netted five or six more.
"I feel that myself," said the Norwegian of the 20-goal target. "I've had about one whole season here and scored about 20 goals in it (1999-2000, 44 games, 17 goals).
"The way we play as well, I get a bit of room in behind the defenders and get crosses into the box. If I can play for a full season I can definitely get 20 goals.
"My strike rate this season is alright, but you always want it to be better. For me, every goal counts now from here until the end of the season. Hopefully I can stay fit for the next and get over 20.
"We create a lot of chances and I could have had another five or six goals this season. The team creates so many chances, which makes it easier for me as well.
"I feeling good now, I don't feel anything from any of my injuries, I've been feeling good for quite a while now.
"It's just up to me now to try and end this season as good as I can."
Sadly, once again, it looks like the season is ending at just the wrong time as far as Steffen's fitness and form is concerned.
"That's been my years at Tottenham unfortunately. It's just for me now to end the season in style and try to score some more goals and get ready for next season and hopefully stay fit for it."
Steffen Iversen is in full agreement with Glenn's assessment that he could be a 20 goals a season man if he stays fit.
