Khairy said it was difficult to deal with such a talented yet problematic player considering what he has to offer the national team.
Faizal has not attended a single training session since scoring 12 goals and being named player of the tournament at the Singapore World League round two last month.
"He is a special kind of player, the star of the team but he is also a character. He goes to training when he wants to, sometimes late, and has terrible discipline.
"But when the time comes he delivers the goods and performs very well. I myself am in a dilemma, what am I supposed to do with a player like this?
"I have been told that Faizal is unhappy with the Malaysian Hockey Confederation (MHC) but I am unsure of what it is,” he said.
Khairy added that since the MHC cannot handle Faizal, he had asked the National Sports Council director-general Datuk Ahmad Shapawi Ismail to meet him and find out what was the problem.
The national squad is currently preparing for the Azlan Shah Cup which would be held in Ipoh this April. Other countries that would be competing includes Australia, India, New Zealand, South Korea and Canada.
