Petrucci struggled for action in Belgium.
He told Inside United: "It was just that sometimes I played out wide and sometimes behind the striker but running beyond him and that is not really my game. However, if the coach tells you to do something, you just try to do it.
"It's always good to be back here but, for me, I am at an age where another loan would be good and a move somewhere else to play first-team football. For the moment, I'm here and will see what happens next."
