Frail is unhappy with Hearts' lack of disicpline

Frail was handed executive power over team affairs on Tuesday and admits indiscipline is a concern.

"Indiscipline has been inherently wrong for a long time," Frail said.

"Having no real leadership or a specific person in charge, it's been allowed to slip, and it's something that'll need to be stopped as of now."

Marius Zaliukas was sent off for striking out at Lee Wilkie in an off-the-ball incident which led to the second goal of Barry Robson's hat-trick.

Lee Wallace saw red for bringing down Robson in the box and Michael Stewart received a second yellow card in the closing seconds for arguing with a Hearts fan.

The midfielder had earlier squared up to team-mate Christophe Berra.

And Frail said: "I have been given the authority to pick the team, whether I'm given the same authority over fining people when it comes to indiscipline I am hopeful, because that is a major factor of what is going wrong.

"We need to cut out petulance but they react to decisions where they think there is an injustice, especially the first sending-off."

Frail felt two of the red cards were questionable and said he would study the incidents on video.

However, he added: "Michael Stewart just needs to be told. He says he was berating a fan who was giving him stick.

"Our fans are great and when they give us praise we are the first to take it but you need to take it equally when they give you stick and in no circumstances can you shout back."
