Meanwhile, Rudan said Krishna has relinquished his role as the Phoenix's designated penalty-taker after he failed to convert for the second consecutive time in a 1-1 draw with Newcastle Jets on Thursday.
Krishna has converted just seven of his 14 penalty attempts during his A-League career and the late miss against the Jets appears to be the final straw.
"I went straight up to Roy afterwards, after all the players went up to our fantastic travelling fans, and I put my arm around him and said 'this is a good test of character for you now. It's happened once, it's happened twice but we'll keep moving forward, you've been great for us and don't be down about it, we'll keep working, keep fighting and make sure you get into those good goal-scoring positions.'
"But he said 'no boss, I'm passing the responsibility on to someone else now'. Those were his words.
"I don't decide on penalty-takers. It really is a confidence thing and for me it's about who is willing to pick up the ball and who is confident in striking it and hitting the back of the net, that's all. We don't practice penalties, it's not a part of the game I work on, but when the players have extras they decide to do it, like Roy.
"But that's the situation right now and I dare say you will see a new penalty-taker, whoever that may be.
The fact they don't practice penalties probably explains a bit. I know you can never recreate the high pressure situation and it probably doesn't make it a thing but I'd still have them practice it. Good on Roy though. At least he's recognised his short comings in this department.
