UEFA is to investigate an incident involving Marko Arnautovic as the Austria forward celebrated after scoring against North Macedonia at Euro 2020.

Arnautovic grabbed his team's final goal in the closing minutes of a 3-1 triumph in Bucharest after coming on as a substitute during Sunday's Group C clash.

Media reports said the 32-year-old directed comments at opposing players in the aftermath, with Austria captain David Alaba seemingly attempting to calm his compatriot down.

The Football Federation of Macedonia submitted an official letter to UEFA demanding the most severe punishment possible following what it described as a "nationalist outburst" towards Ezgjan Alioski, who has Albanian roots.

Arnautovic, who is of Serbian descent, issued a statement via social media on Monday to apologise for "some heated words".

Serbia does not recognise the independence of its former province Kosovo, while there is historic tension between Serbia and North Macedonia.

"There were some heated words yesterday in the emotions of the game for which I would like to apologise - especially to my friends from North Macedonia and Albania," Arnautovic posted on Instagram.

"I would like to say one thing very clearly: I am not a racist. I have friends in almost every country and I stand for diversity. Everyone who knows me is aware of that."

UEFA said on Tuesday: "In accordance with the article 31(4) of the UEFA disciplinary regulations, an ethics and disciplinary Inspector has been appointed to conduct an investigation regarding the incident involving the player Marko Arnautovic that occurred during the 2020 European Championship group-stage match between the national teams of Austria and North Macedonia on 13 June 2021."

Austria are next in action on Thursday, taking on the Netherlands - who defeated Ukraine 3-2 in their opening fixture - in Amsterdam.

Marko Arnautovic has apologised for his heated celebration after scoring in Austria's win against North Macedonia but has denied using a racist slur.

The 32-year-old was brought on at half-time in Sunday's Group C clash and rounded off the scoring in his side's 3-1 victory at the National Arena in Bucharest.

Arnautovic, who is of Serbian descent, appeared angry as he celebrated and had to be calmed down by captain David Alaba.

He was accused of yelling an alleged racist insult at North Macedonia players Egzon Bejtulai and Ezgjan Alioski, who both have Albanian roots.

Serbia does not recognise the independence of its former province Kosovo, and there is historic tension between Serbia and North Macedonia.

However, former Stoke City and West Ham man Arnautovic took to social media on Monday to deny allegations that he is racist.

"There were some heated words yesterday in the emotions of the game for which I would like to apologise - especially to my friends from North Macedonia and Albania," he posted on Instagram.

"I would like to say one thing very clearly: I am not a racist. I have friends in almost every country and I stand for diversity. Everyone who knows me is aware of that."

Austria's next Group C outing is against the Netherlands in Amsterdam on Thursday.

The Netherlands edged a 3-2 thriller with Ukraine in the pick of the Euro 2020 matches to date, while England and Austria also got off the mark in their opening group games on Sunday.

Denzel Dumfries was the late hero for the Oranje with his first international goal to sink Ukraine, who had battled back from two goals down in Amsterdam to temporarily level things.

Austria also left it late to see off minnows North Macedonia 3-1 in Bucharest earlier in the day and England beat Croatia 1-0 at Wembley through a well-taken Raheem Sterling strike.

Using Opta data, Stats Perform looks at some of the best facts from across Sunday's entertaining action at Euro 2020.

England 1-0 Croatia: Three Lions make winning start at Wembley

Sterling's first goal at a major international tournament in his 13th appearance was enough for England to overcome Croatia in a repeat of the 2018 World Cup semi-final.

Croatia offered very little in response as England made it 11 straight victories in games in which Sterling has scored – the best-such win rate of any player in the nation's history.

The Three Lions are now unbeaten in 12 games at Wembley in major tournaments (exluding penalty shoot-outs), winning eight and drawing four of those matches.

The victory for Gareth Southgate's side in their Group D opener was their seventh in a row in all competitions – their best such run since March 2015 under Roy Hodgson.

It was also the first time England have won their opening game at a European Championship finals in their 10th participation in the tournament.

That is in contrast to Croatia, who lost their first match in the competition for the first time, having won four and drawn one of the previous five.

The contest was also a special occasion for England substitute Jude Bellingham, who at 17 years and 349 days became the youngest ever player to feature at the Euros.

Austria 3-1 North Macedonia: Substitutes strike late to deny tournament debutants

North Macedonia's first ever game at a major tournament ended with a late defeat to Austria in Bucharest.

Aged 37 years and 321 days, 120-cap Goran Pandev became the second-oldest goalscorer in the competition when cancelling out Stefan Lainer's opener.

That was just Lainer's second goal for Austria, with his only other international strike coming against North Macedonia in qualifying.

Michael Gregoritsch and Marko Arnautovic were introduced to snatch the three points for Austria – their first ever win at the European Championships in what was their seventh game.

In doing so, Gregoritsch and Arnautovic became the first pair to score from the bench for the same country in the competition since Michy Batshuayi and Yannick Carrasco for Belgium (v Hungary) in 2016.

Arnautovic's goal to make certain of the win was his 27th for Austria at senior level, with three of those coming against North Macedonia – more than he has managed against any other country.

Netherlands 3-2 Ukraine: Oranje leave it late to edge thriller

The Netherlands ended a run of four straight defeats at the European Championship with a dramatic victory against Ukraine in Amsterdam.

All five goals were scored in the second half, making it the highest-scoring fixture in the competition's history after a goalless first half.

The first half may have ended scoreless, but the tempo was set early on as there were nine shots in the opening 10 minutes – a tournament record since Opta started recording such data in 1980.

Georginio Wijnaldum opened the scoring in the 52nd minute with his 15th goal in 26 appearances for Oranje, having scored only eight times in his first 50 games for his national side.

Wout Weghorst added a second soon after, but Andriy Yarmolenko pulled one back with a sublime strike to end a run of 72 shots without a goal for Ukraine at the Euros.

From the visitors' very next attempt, Roman Yaremchuk headed in an equaliser to seemingly steal a point at the Johan Cruijff ArenA.

But Dumfries found the back of the net in the 85th minute, making it the latest game-winning goal for the Netherlands at the Euros since current boss Frank de Boer scored an 89th-minute penalty against Czech Republic at Euro 2000.

Austria finally registered a first European Championship win at the seventh attempt as they ruined North Macedonia's first outing at a major tournament with a 3-1 triumph in Bucharest.

Substitutes Michael Gregoritsch and Marko Arnautovic both scored in the final 12 minutes to make sure Franco Foda's side claimed all three points from the Group C tussle.

After fellow debutants Finland recorded a 1-0 triumph over Denmark on Saturday, North Macedonia had appeared on course to mark their maiden appearance with a point against opponents who beat them twice in qualifying.

Having struck in the second leg to see off Georgia in the play-offs and secure a spot at Euro 2020, Goran Pandev became the second oldest scorer in the competition's history when he capitalised on an unexpected opportunity to tap in an equaliser.

Goalkeeper Daniel Bachmann failed to hold on when sliding out to grab the ball ahead of Aleksandar Trajkovski, a three-way collision also involving David Alaba allowing the ever-alert Pandev to convert into an unguarded net with his team's first attempt.

Austria had opened the scoring with an eye-catching goal, Marcel Sabitzer's raking pass finding the advancing Stefan Lainer, who showed impressive attacking instincts for a defender with a side-footed volley from a tight angle that flashed beyond Stole Dimitrievski.

There was not so much to admire about the build-up play and finish for North Macedonia's equaliser, not that they cared too much.

Arnautovic was summoned from the bench early in the second half to try and inspire Austria, though it was fellow replacement Gregoritsch who scored the game's crucial third goal, the Augsburg forward making a near-post run to apply the finishing touch to Alaba's inviting cross from the left flank. 
 
Any hope of a tiring North Macedonia rallying for a second time disappeared when Arnautovic went clean through in the 89th minute, calmly rounding Dimitrievski to wrap up the victory. 

What's next?

Both teams are back in action on Thursday. North Macedonia will be remaining in Bucharest for their second fixture, against Ukraine. Austria, meanwhile, move on to Amsterdam to take on the Netherlands.
