Meanwhile in a message to fans Allardyce said: “We’ve now drawn away from that danger zone, so we need to chill out a little bit and make sure we produce the performances in our final six games that are as best as they can be to try to get as many points as we can.
We’ve taken the pressure hugely off ourselves so we can really have a go at Liverpool now.
“I know the players will give their all on Sunday and let’s hope that’s enough to upset the leaders of the Barclays Premier League.
