Japanese club Kawasaki Frontale have become increasingly difficult to deal with on their sojourn to Australia. The club has bought with them 48 personnel - almost double of what their opponents Central Coast Mariners took to Japan - and have made various requests in regards to comfort and safety.

Reports have suggested that the club booked an extra night at their hotel so that all rooms were ready for them, travelled business class, refused to train at a ground due to the grass being too long, had their orange juice tested in case it was tampered with and have spent $30,000 extra on the Mariners' host accommodation and meal bill.

Then to top it all off, coach Takashi Sekizuka was caught in a press box at Bluetongue Stadium spying on the Mariners at training.

Mariners coach Lawrie McKinna said Sekizuka's actions were against protocol seeing as they wanted their own closed session.

"it's just unusual that they ask for a closed venue then turn up at our training. I think it's a wee bit cheeky but I don't think he would have learned too much," McKinna said.

"He probably would have learned that Paul O'Grady looks double the size of some of his players."
