Sam Allardyce: "The next window of international break comes on October 6, so if he's fit before then we'll have done a magnificent job, but I probably don't think so.
"I think it will be after that.
"If the lads do the job they've started to do then it won't be too desperate to rush him straight back.
"He's not had a lot of pre-season because of the European Championships and he didn't have a lot of football at Liverpool.
"We've got to be very careful that we don't rush it too much and the hamstring might reoccur because that would be a disaster for us and for him."
