Criticism of England’s performances had grown in recent months so it felt a big night for the Lionesses and manager Wiegman.
Spain, buoyed by their stoppage-time victory over Belgium on Friday, started off as the stronger of the two sides with Paralluelo causing problems down England’s right-hand side.
But Bronze marshalled her well and England’s backline, led by captain Leah Williamson, stood solid, forcing Spain deeper as they resorted to shots from outside the box.
Momentum swung in England’s favour midway through the half and they capitalised with James drifting past defenders on one wing, as Park battled and tricked her way through on the other side.
Arsenal striker Alessia Russo, who was on the scoresheet in last week’s 1-1 draw with Portugal, impressed yet again and it was her weaving run that led to Park’s opener.
Wiegman had called for more ruthlessness last week and England made no mistake this time around, capitalising on their momentum and rattling Spain.
A response was expected and the world champions continued to create chances but goalkeeper Hannah Hampton, selected ahead of Mary Earps as they continue to battle for the number one spot, made a strong save to deny Ballon d’Or winner Aitana Bonmati.
Claudia Pina and Garcia had further chances for Spain but England remained composed, maintaining pressure and using their width effectively, while centre-backs Williamson and Millie Bright blocked countless shots.
James thought she had made it 2-0 with minutes remaining but Spain goalkeeper Cata Coll recovered to gather in her strike on the goalline with substitute Chloe Kelly lurking dangerously nearby.
But if England supporters needed reminding of their quality, this was a performance to do so.
Spain on the other hand have had to deal with plenty off the pitch this week – former federation chief Luis Rubiales was found guilty of sexual assault – and this was one battle too far for them.
They have ground to make up in the defence of their Women’s Nations League title and it will no doubt be another blockbuster showdown when these teams meet again in June.
