Carroll did not score in the 3-0 win against Fulham but the powerhouse will play a big part in West Ham’s season.
Allardyce said: “If Andy scores between 10 to 15, it is going to give us a great chance to be out of the relegation zone.
“If he gets 15 to 20, we can get into the top 10 because all we have to do is to produce enough clean sheets to make sure we get points on the board with the goals that he scores.
“Kevin Nolan can feed off him as happened at Newcastle. By the time Andy had been transferred to Liverpool, he had scored 11 goals and by the time Kevin finished the season, he had 13.”
