EURO star Stelios has flashed a warning to Arsenal of the perils of under-estimating the underdog ahead of Saturday's FA Cup showdown with Wanderers.

The Reebok star proudly showed off the medal he won when he helped rank outsiders Greece win the European Championships in Portugal last summer in one of the biggest sporting upsets of all time.

"The gaffer and the players kept asking if they could see it, so why not?" said the Whites midfielder. "It can be a good motivation as we get ready for Saturday's game.

"I look at it sometimes and it reminds me of who I am and what I have done. It helps to keep you going."

Arsenal are favourites to reach the semi-finals but Stelios, who scored the winner at the Reebok in January when Wanderers dealt a savage blow to Arsene Wenger's title ambitions, is aiming to cause another upset.

"The FA Cup is maybe the most famous cup in the world and it would be a great honour for myself and for Bolton to win it," he said.
