Big Sam has just realised that we could have a bit of a relegation battle on our hands if things get any worse, so a win against troubled Hull would be a big boost to the club.
Allardyce said: "We are not out of trouble, not by a long chalk and it is going to be a tough game against Hull.
"Although nobody has had to get that 40-point tally for many years, it is the magic number to stay up. That is where you have got to get to as quickly as you can."
