Bournemouth manager Eddie Howe praised his team's resilience after the 1-0 win over Scunthorpe kept their promotion push on course.
Brett Pitman's fifth goal in as many matches took his tally to 15 since returning to the club from Bristol City. Pitman's goal came in the 11th minute with a volley after Marc Pugh and Matt Tubbs had opened up the Scunthorpe defence.
After watching the Cherries claim their fifth successive win, four of them without conceding a goal, said: "This was not our best performance. We were well in control but we could not turn our possession into chances and goals.
"We created enough to have won by a bigger margin but it was always going to be hard against a team fighting for their lives. Our problem is that we have played more matches than most of our rivals so I think we must win all four of our last matches. I have every faith in the players and I would not ask it of them if I did not think it was possible.
"Scunthorpe outnumbered us in midfield but we still had far more of the ball and I do not think there is any doubt that we deserved to win."
Scunthorpe goalkeeper Eirik Johansen, on loan from Manchester City, made important saves from Harry Arter, Matt Ritchie and Eunan O'Kane. Pitman also hit the crossbar in the second half as Bournemouth got on top but Scunthorpe should have equalised in the 54th minute.
Mark Duffy cut in from the left but dragged his shot wide from 15 yards with the goal at his mercy. Scunthorpe manager Brian Laws admits his club face a huge task staying in npower League One after the latest setback.
"Credit to my players," he said. "They have not given up and they showed that here. If we put in similar effort over the rest of the season we have got a chance of succeeding. It is a pressure situation.
"We have a huge job on our hands and it is going to take a lot of effort to get out of this trouble. As I see it, I think it is between ourselves, Oldham and Colchester as to who goes down.
"We have to start scoring away goals. This was the fifth match in a row we have not scored away and it is a real Achilles heel. Mark Duffy's early miss in the second half epitomised what has been going on. He got into the goalmouth and did not even hit the target. He should have buried the chance."
