Denzel Dumfries headed a dramatic late winner to earn the Netherlands victory after Ukraine had come back from 2-0 down in a Group C thriller in Amsterdam.
Oranje boss Frank de Boer is hoping to use Euro 2020 to prove to fans he is the right man to lead the team into a successful new era after an unconvincing start in the role.
It looked like going to plan for De Boer when Georginio Wijnaldum, who scored eight times in qualifying, pounced from inside the box before Wout Weghorst’s instinctive finish doubled the lead.
But Ukraine pulled one back through Andriy Yarmolenko’s outstanding 25-yard dipping finish and, four minutes later, Roman Yaremchuk headed the equaliser to silence the Dutch fans.
However, Dumfries’ excellent 85th minute header, after substitute Nathan Ake’s cross, earned the Netherlands victory on their return to the major tournament stage after a seven-year absence.
Will the Oranje be Euro 2020’s great entertainers?
De Boer headed into Euro 2020 on the back of 11 games in charge that have seen five wins, four draws and losses to Mexico and Turkey. Not all fans are convinced he is the right man for the role.
Yet his team of youth and experience showed grit and determination to edge the highest scoring game of the tournament so far – much to the delight of most of the 16,000 fans inside the ground.
While 19-year-old defender Jurrien Timber made just his third appearance for his country, Maarten Stekelenburg started in goal at the age of 38.
It was Stekelenburg’s opposite number, Georgi Bushchan, who looked like frustrating the hosts as he made excellent saves to keep out Memphis Depay and Wijnaldum before the latter opened the scoring, the first of five goals in 33 minutes.
Yarmolenko’s long-range finish to begin Ukraine’s comeback was the pick of the bunch but it was Dumfries’ header that lifted the roof as the Netherlands got their campaign off to a winning start.
Both teams are back in action on Thursday. While Ukraine take on North Macedonia in Bucharest at 14:00 BST, the Netherlands entertain Austria in Amsterdam at 20:00.
