But they had the possession and chances to win the game.
Mac Allister has now converted five spot kicks this season.
He told The Final Whistle on BBC Sussex: “I always get nervous but at the same time I am very confident in myself and I knew I was going to score.
“It is really nice to score but as a team we wanted to win and we couldn’t.
“I have a routine and I take some seconds to relax and focus on the ball.
“I think it is the best way to tale a penalty or a free-kick.”
Mac Allister was disappointed with the draw.
He said: I think for the neutral it was a good game.
“For us it wasn’t because we wanted to win.
“We deserved to win but at the same time we made many mistakes and it is not nice that they scored three goals.
“We have to keep working on these details because it is what is going to get us in Europe.”
