Speaking to the Nottingham Evening Post on Monday, Mullins said "It was nice to be in the team again after a spell on the sidelines - no one likes to be on the bench, now I am in, I don't want to be out again, so I hope I've done enough to convince the boss.
"Like every player, there is room for improvement and I know I have things to work on, but the main thing is to be playing."
"I thought in the first half (at Boston) we weren't really at the races. They bombarded us with the long ball as we expected and we went in 1-0 down.
"But we said at half-time we were capable of getting back into the game and going on to win the game and in the end we nearly did because in the second half it was all us.
"On another day we might have scored a winner but first and foremost it was important to stop the rot and not lose.
"It was vital to get a goal after the run we've had away and it was great to see Richie get it. Hopefully now he can go on and score in a few matches in a row.
"If he does that then we will start picking up some results and moving up the table."
