Former Greece captain Giorgos Karagounis has challenged Claudio Ranieri's Premier League winning Leicester side to a friendly match against his country's XI which won the European Championship in 2004.
The 39-year-old, who retired from football after the 2014 World Cup, was part of the Greece team who went from never winning a game at a major tournament to lifting the trophy in what many consider to be one of the greatest underdog stories of all time.
Karagounis worked alongside Ranieri during the Italian's short and unsuccessful stint with the Greek national team in 2014, just seven months before he became Leicester boss and took the Foxes to their first ever Premier League title.
So which achievement is bigger? Speaking exclusively to Goal , Karagounis admitted there was only one way to find out - by organising a friendly game between the two sides.
"Both are huge and the biggest surprises in the history of football", said Karagounis.
"If we want to see which is the bigger achievement then I need to talk with my friend Claudio Ranieri and we can arrange a friendly game and see who is the best team - we are still in good shape!
"Well, seriously what Leicester did last year was huge. This team had to be in shape all season while Greece did it in a month playing against big teams, the likes of (Zinedine) Zidane. It’s different but they are both as important as each other."
Leicester are currently 13th in the Premier League, while Greece are second in World Cup qualifying Group H, level on points with leaders Belgium.
