"If we get beaten, and the two teams chasing us end up winning, then we would find ourselves right in amongst it again. There will be no easing up.

"History tells you that 38 points might be enough but I don't think we can rely on it. We might need a bit more, we might need a bit less," he added.
"But the fact of the matter is that we have got eight games left with five of them at home and we want to cross the finishing line as soon as possible."
