"I was pleased to be playing again," he says, "but I was disappointed with my performance on the day.
"It was hard work and personally, I am trying to improve and I didn't do that on Saturday.
"So I have just got to keep working hard in training to try and pick up next time."
Looking at the game overall, he adds:
"When you go 1-0 up you want to win; we knew it was going to be an ugly game and that we would have to grind it out but it wasn't to be.
"Everyone in the ground could see the performance of the referee and linesman left a lot to be desired.
"We scored a good goal in the first half which was disallowed and then he has given a free kick for handball that wasn't.
"The 'goal' was a good build-up and it didn't even look like it could have been offside because the ball came backwards."
It was Carl himself that was adjudged to have handballed, leading to the free kick from which Plymouth equalised, and he says:
"The lads were very disappointed to say the least and with the free kick he had even let them play on for a bit - and then came back and gave them it.
"It didn't even strike me on the arm at all, it hit me in the stomach and when things like that go against you it is a little bit disappointing - but hopefully they even themselves out over the year.
"Maybe tonight we will have a referee who is a West Ham fan!"
Carl, a Welsh international, is looking forward to the game and says:
"Their fans are very passionate and it should be good."
Meanwhile, reflecting on Andy Melville's recent decision to retire from international football for Wales, he says:
"He has been a long servant and is a fantastic pro - it is definitely a big loss for Wales but obviously Andy felt it was the right time and the best of luck to him."
