Local fans turned on their players during the 1-0 loss.
"The system doesnâ€™t count for very much. We have to improve individually and give much more to the team,â€ť slammed Petkovic.
â€śWe are still tired and lacking the right mentality. This really isnâ€™t good enough and some players have to give more. I want players who give their heart and soul. Weâ€™ve got to work harder and anyone who doesnâ€™t understand that simply wonâ€™t play.
â€śWill we bring in different players on the transfer market? I am focused on working with the squad I have.â€ť
