Pedro struck three times and Cole Palmer also scored as the Blues won 4-1 on the night.
"It was a dream night for me," he said. "Since I joined Chelsea, I’ve been dreaming of these moments to play for a big team and get my hat-trick – and I think it was a perfect night to get my first hat-trick.
"We just need to keep moving forward. I’m just living my dream here. I’m very grateful to everyone who has helped me on my journey."
Pedro also said of the win: "I think everyone was perfect. When the team plays like this, I will get chances. I think everyone was top. It was a special day – everyone did a brilliant job. We still have nine games to look forward to and fight to be in the top four.
"All my goals came from being in the right place at the right time. The team expects that from me. The goals were always important."
