Palmer's treble came before halftme, with two of his three goals coming from the spot. He is now the only player to have netted three first-half hat-tricks in the Premier League era.
"It feels good to get three points and score some goals," Palmer said afterwards. "It was a good one in difficult conditions today. As long as I can keep scoring hat-tricks, I’m happy.
"I think we did well in the first half. The second half was a bit flat, but, personally, it feels good to get back on the scoresheet.
"I don’t really pay attention to milestones, but when you see them, it’s nice."
The England midfielder also admitted: "I’ve never been injured before in my career. This is something new to me, and I’m still finding out how to deal with it.
"It has been frustrating, I don’t feel like I’ve played a game this season fully fit. I’ve been going into games thinking, 'Can I do certain things? Can I not?' Overthinking it.
"The staff have been really good. I’ve been working closely with the physios on a day-to-day basis. They have all helped, and I’ll get through it.
"I’m not here to make excuses, and I’ll get over the injuries. I know what I can do when I’m fit, and hopefully I can get back to that soon. For now, I just manage it and get there."
