From a Sheffield Utd fan:
"Jamie Murphy sold, £2 million plus add-ons to Brighton.
He's great on his day, easily one of the best players in the league, but is so inconsistent and gets bullied out of games. I'm gutted he's gone as it's not a good time to lose one of your better players, but it's also a good fee. However, it won't be if we waste the money/don't spend any of it."
He was too lightweight. Regardless, he was a fantastic player, but getting a move to Brighton doesn't change any of his attributes.
