Greece raced into a two-goal lead before the break, with Giannis Konstantelias opening the scoring 20 minutes in before supplying the assist for Konstantinos Karetsas to double their advantage.

Konstantelias turned provider again just 13 seconds into the second half, setting up Christos Tzolis for Greece’s third, which proved to be the final nail in Scotland’s coffin as the hosts failed to find any kind of response.

The result confirmed Scotland's relegation from League A of the Nations League, with Clarke's men unable to hold onto the 1-0 advantage they earned in Piraeus.

Speaking to BBC Sport, Clarke admitted Greece was a deserved winner.

“They scored with their first attack. We didn't get back behind the ball quick enough and we didn't create enough. That adds up to a disappointing night,” he said.

“I'll go away and look at myself to see what I could have done better. Maybe I didn't make enough rotations. Maybe I could have made more to freshen the team up.

"I talked before the game about setting down a marker — I think Greece have done that tonight.”

Midfielder Ryan Christie echoed his manager’s words, saying: "We probably didn't create enough and they were pretty cut-throat going forward themselves.

"Overall, a very frustrating night at Hampden, but we've got to pick ourselves up for the friendlies in the summer.”

Christie was also quick to address the disappointment felt by the fans, adding: "You try and remember this feeling, how much you feel you've let the fans down at Hampden tonight, so that when the qualifiers come you don't do it again."

Despite the loss, Clarke remains optimistic about Scotland’s potential, stressing the importance of their upcoming friendlies against Iceland and Liechtenstein as preparation for the World Cup qualifiers later in the year.

“We've learned that when we do everything right, with the ball and without the ball, we're a good team at this level," he said. "We've got two friendlies in June to prepare for the World Cup qualifiers in the autumn."

Scotland’s performance came as a surprise given their solid home record, having lost just two of their previous 22 competitive international matches at Hampden Park — versus Ukraine in 2022 and Poland in 2024.
