The Real Madrid midfielder curled home a stunner from outside the area to put Turkiye 2-1 up midway through the second half and become the youngest player to score on his Euros debut, with Kerem Akturkoglu confirming the win after a wave of Georgia pressure. 

Ahead of the encounter in Dortmund, fans from both nations were involved in scenes of violence inside the stadium as torrential weather conditions threatened to postpone Georgia's maiden bow at an international tournament. 

Turkiye led in the 25th minute, as Mert Muldur, who had scored just once before for his nation, fired home a goal of the tournament contender with a sweet volley into the top corner. 

The Turkish supporters packed into Westfalenstadion were in raptures when they thought their side had doubled their advantage two minutes later, only for Kenan Yildiz's effort to be disallowed for offside by VAR. 

And a moment of history arrived for Georgia when Georges Mikautadze neatly flicked a finish beyond Mert Gunok at the near post.

Yet Turkiye's lead was restored when Guler picked out the top-left corner, breaking a record set by Cristiano Ronaldo in 2004 in the process.

Georgia went agonisingly close to an equaliser – Giorgi Kochorashvili hitting the crossbar and drilling off target from close range while Khvicha Kvaratskhelia struck the post and Samet Akaydin made a goal-line block.

But with Georgia goalkeeper Giorgi Mamardashvili up for a corner deep in injury time, Turkiye broke and Akturkoglu placed the ball into the empty net to settle a thrilling Group F clash.

In a match that featured 36 shots and a combined 4.3 xG, Guler's sublime effort saw him become the youngest Turkish player to score a goal in the history of major tournaments at just 19 years and 114 days.

Turkiye became just the second team ever to start a match at the Euros with two teenagers (Guler and Kenan Yildiz), after Hungary did so in 1964. 

Mikautadze scored Georgia's first-ever goal at a major tournament, meanwhile. He has now netted six goals in his last six starts for his country.
