Republic of Ireland coach Giovanni Trapattoni believes that any of the 16 competing nations can win the European Championships this summer.
Despite accepting that there are favourites to lift the trophy, the Italian has pointed to Greece's success in 2004 as the reasoning behind his opinion.
"In football at the moment, anything is possible," Trapattoni told reporters.
"The teams are very strong. Spain, England, Holland, Germany - usually these four, but I remember Greece."
Trapattoni took charge of Ireland in 2008.
