Pitch invasions 'a bad look' - but Clarke praises Tartan Army

Was it to the Tartan Army's credit, he was asked, that none of the supporters came on to the grass at Hampden Park?

"Absolutely," he replied. "It just shows that you can enjoy yourself without going on the pitch. There's no need for people to go on the pitch.

"The way it ended with the scenes on Saturday at Celtic Park is not good for Scottish football. It's a bad look. It doesn't do anybody any favours."

Hearts had said "reports of serious physical and verbal abuse towards our players and staff, both on the pitch and elsewhere" would be investigated by Police Scotland.

Meanwhile, the Scottish Professional Football League was waiting for the match delegate's report to consider action.

"It's much better if the people could celebrate but stay where they should stay," Clarke said. "People invading the pitch is not right, because player safety is endangered and that's not correct anywhere."

He told the media as he announced his squad for the World Cup: "There's no way that people are going to come in through that door and try to disrupt you guys doing your job here. It's just not correct.

"On the pitch is the player's place of work. People should not go on the pitch. It's quite clear."
