He told the club's website: "I am proud of my performance this season. I have set targets each month and have hit them, but there is still more to do. I want to become the best version of myself on and off the pitch, and that's what I aim to do.
"I never get comfortable and I always strive for more. For example, at the start of the season, I aimed for 15 goals. I recently hit 20 and now I'm close to 25. If you believe in yourself there is no limit.
McNeilly also said: "It's a huge moment. This is the biggest game of my career so far. It would be an unbelievable feeling if we win, and to do it under the lights will be even bigger.
"It has been a special season already and I wouldn't have changed any of it especially the group of players.
"Playing at Stamford Bridge means everything to me and I need to make my performance count. I will prepare in the same way as I do for any game, being focused and in the zone."
