Just to give you both sides of the coin, and to irritate everyone on this forum one last time...
I personally felt that he was a massive burden on the team for large parts of last season. He takes far more shots than anyone else, but often does them at times when he could play someone else in. Largely greedy, and not very good in an intelligent passing and moving team.
There are times next season when you'll need to dig in to get a result, and Murphy is exactly the kind of player you do not want on the pitch during this time. It can feel like you're playing with 10 men a lot of games, with the odd spark that will impress you.
In contrast to what someone else said, I did feel as if there were many times last season his attitude let him down. He visibly looked like he couldn't be bothered a lot of the time, mind you it didn't help that the manager was picking him regardless of his last 10 absimal perfomrances.
He can be exciting at times, and may well score you a few goals. He wasn't anywhere near consistent enough for League 1 however, so will be interesting to see how he progresses now. Scores 3 against top of the league Gillingahm, but then looks Sunday League against Doncaster. Go figure.
Best of luck for the season.
