Neal's last two performances in the victories against Bury and Carlisle have drawn praise from his team-mates and the Vale staff alike.
The 27-year-old made a string of fine saves as the Valiants overcame the Shakers in the Johnstone's Paint Trophy last week.
On Saturday, he had little to do against the Cumbrians but excelled on the one occasion he was called into action and kept his first clean sheet of the campaign at Brunton Park.
"He has been our best player this season by far, his consistency levels have been super," Grew told the club's official website.
"I don't want to tempt fate but some of his saves have been superb. On Saturday he didn't have much to do really, but he made one great save when they hit the bar then after that he had come for every cross.
"He has never fumbled a cross and his kicking was excellent. His all-round game at the moment is top notch."
