It is a remarkable turnaround for Vilda and a squad that is not even at full strength in Australia and New Zealand because of the very public disagreement. Moreover, there were hints even coming into the World Cup that all was still not well in the Spain camp. Perhaps they are still not.
But Vilda's side stuck together to defeat the 2019 runners-up the Netherlands 2-1 in extra time and will face Sweden in the last four on Tuesday. Even on the eve of Friday's game against the Dutch in Wellington there was no escaping the turmoil which had threatened to torpedo Spain's World Cup in the past year.
"The team is united," Vilda said, asked by a Dutch journalist to comment. "We have a group that competes and they are all fighting for the same objective, and they are very motivated."
Row explodes
Discontent between players on the one side and the Spanish football federation (RFEF) and Vilda on the other had been brewing for some time. In September 2022 the situation exploded - 15 of the squad emailed the RFEF to say they did not want to be considered for selection, citing their "emotional state".
They were unhappy with numerous things: the atmosphere around the camp, Vilda being too strict and the team's lack of success under the coach since his reign started in 2015. The players also objected to travel arrangements and organisation behind the scenes, but the bulk of their complaints were aimed at the 42-year-old Vilda.
The RFEF backed the coach however and he omitted the protesting players for friendlies against Sweden and the United States, which Spain drew and won respectively. Indeed, including at this World Cup, Spain have lost just twice in 17 matches since the mutiny broke out, validating the RFEF's stance and strengthening Vilda's position.
When Vilda named his squad for the World Cup, three of the 15 protesting players were selected - Aitana Bonmati, Mariona Caldentey and Ona Batlle, all at Barcelona. They had stepped down from their position, ostensibly satisfied that sufficient improvements had been made in the areas the players demanded.
But the absence of another Barcelona trio in Patri Guijarro - who struck twice as they won the Champions League - Mapi Leon and Sandra Panos were all expected to hurt Spain. In the build-up to the World Cup, Vilda said that the conflict was "practically resolved". But refusing to return, Mapi Leon said: "I can't go back, there has to be changes."
