Speaking after the game Magilton said: "I am disappointed because obviously we started the game very brightly, got a very good goal and then conceded ground and conceded possession too easily for me.
"I have spoken about this team before with regards possession of the football and I don't think we have done that too well today.
"As much as we defended very well and stoutly all day I would like us to have a little bit more quality with the ball and I don't think we did particularly well with that again."
Magilton was also far from happy with the performance of referee Kevin Friend feeling upset by the penalty decision that went against David Wright: "With minutes to go, I think it was a very, very harsh decision.
"I have to say I was astounded to find that this referee was refereeing this game again today because he did last year and he sent one off and booked six and today he's sent one off and there were more bookings."
Ian Holloway was taken to hospital before the game, but assistant Argyle boss Tim Breacker said he's on the mend: "Just before the end of the game, the club doctor informed me Ollie's fit and good and on his way home now.
"I haven't spoken to him personally but the club doctor told me Ian had a kidney stone, which can be very painful.
"I am sure he will soon be back to his bubbly self and we wish him well. Hopefully I will get to speak to him soon."
Of the game itself Breacker continued: "We gave ourselves a mountain to climb and they played a different shape, which we thought they might, and that threw us a little bit as well.
"But gradually we got back into it and got the goal, although we did not get ourselves much time to get another one."
