Errol Gulden is back to his best just when the Swans need him. Gulden is now cementing himself as a critical part of the Swans’ premiership push. Errol Gulden walks down the race after being injured against Brisbane in March. The Swans need midfielders capable of hunting for the ball, but Bolton wants Gulden stay on the outside where he can do maximum damage. The Swans need that one player who’s going to really steel themselves inside.
