"I feel like today it's a lack of professionalism, we could have ended the game in the first half, this game could have ended with 5, 6, 7 or 8 goals, but we did not convert the opportunities that we had," Nabi told journalists.
"Sometimes you don't score because it's a lack of collective, sometimes ego. If you don't respect football, football won't respect you.
"I am very very frustrated, very frustrated about the two points that we have lost today because we controlled the game from the first minutes until the last minute, but that is what happens when you let the opponent live," he added.
"Sometimes if you can't score, or convert your chances, if it's only three, or four minutes left, at least defend your lead then, so I don't understand what happened today."
