The Teen Prodigy Who Changed Greece's Game

Scotland entered halftime with a valuable 1-0 advantage in Athens, but the emergence of 17-year-old Kostas Karetsas in the second half completely transformed Greece's offensive threat. The Genk midfielder, making his senior international debut after switching allegiance from Belgium, nearly orchestrated a dramatic comeback with his fearless attacking play.

Karetsas: From Belgian Youth Star to Greek Hero

• Born in Genk to Greek parents, developed through Belgium's youth system
• Made professional debut at 16 for Genk, becoming a Jupiler Pro League regular
• Played for Belgium U21s as recently as November 2023
• Greek FA won hard-fought battle for his international allegiance

"My heart beats only for Greece - my homeland fulfills me completely," Karetsas declared after his electrifying debut.

Tactical Game-Changer

The teenager's second-half introduction saw:

• 78% pass completion in final third (highest among Greek players)
• Created 3 chances including Tzolis' hit post
• Completed 4/6 dribbles against Scotland's defense

BBC Scotland's James McFadden observed: "He looked classy, composed, and became their only attacking outlet. I'd be stunned if he doesn't start at Hampden."

Scotland's Defensive Dilemma

Steve Clarke faces key decisions:

• Stick with Robertson 1v1 against the teenager
• Consider double-marking system
• Adjust midfield cover for overlaps

Veteran goalkeeper Craig Gordon warned: "We haven't seen many debuts like that from someone so young. He's someone we'll need to look out for."

Second-Leg Preview

Sunday's clash at Hampden Park promises:

• Karetsas likely to earn first international start
• Scotland's physical approach vs Greek technical play
• Set pieces could prove decisive (Greece conceded 7 of last 10 goals from dead balls)

Karetsas remains confident: "If we play like the second half, we will win in Scotland."

For Steve Clarke's side, containing this teenage sensation may be the key to securing Euro qualification.
