Is this really England's toughest test? After all, Belgium are ranked 28th in the world, while England are fourth.
"Don’t be fooled by their world ranking," says England boss Mark Sampson.
"This is a Belgium team who have beaten both Norway and Denmark, and their most recent result was a 5-0 win against a strong Russia team, so they will without doubt provide our biggest challenge on home soil in recent years.
"They are a genuine rival to us achieving our aim of top spot in this group."
A real chance, then, to see just how far England have come since finishing third at last year's World Cup.
