Speaking to the Official Club Website, Magilton said: "The players deserve a lot of credit for the way they responded after what has been a difficult week with the two home defeats. They all showed terrific character and the win will give everyone a lift.
"We've got to take confidence out of the performance and most importantly the result, because we needed a win, and push on from here and look to put together a decent run of form.
"There is a lot more to come from this side, we know that and having been three goals up, I wasn't too pleased that we let them back in the game and gave them a sniff of a chance, me being the perfectionst that I am.
"But we held firm in the end and in patches we played some very good football and I don't think anyone can argue that we didn't deserve the three points.
"I have to pay tribute to Southend though. They kept trying to pass the ball and that is to their credit. They are certainly deserving of being in this division."
