Scunthorpe boss Brian Laws felt he could take plenty of positives from his side's performance in the draw against Shrewsbury.
The Shrews fought a rearguard battle at Glanford Park. The visitors failed to muster an effort on target for 80 minutes until substitute Tom Bradshaw finally tested goalkeeper Sam Slocombe from long range.
Despite dominating most of the possession, Scunthorpe could not make it count and were held to a goalless draw, leaving them still with only one home win all season.
"We have had 70% of the ball and created some good chances, but our cutting edge deserted us," said Laws.
"Of course it was a game we needed to win and I am disappointed we didn't, but there are plenty of positives we can take from a performance like this. The fans know when we have put on a good shift and they stayed right behind us.
"It's the first time we have kept a clean sheet for some time, so we have got to be happy with that. Our home form has not been good but we have now drawn both games here in 2013, so that is encouraging."
Laws knows he desperately needs got strengthen during January if Scunthorpe are to stay up.
He added: "If things work out, I would like to bring in two, possibly three players, but we may have to be patient.
Meanwhile, Ellington could be on his way back to Ipswich after a injury-hit first month at Glanford Park. He limped off again in what was his home debut with a hip injury.
"We will make a decision next week," said Laws.
