It's important to look at the teams' recent performances in their respective qualification campaigns or friendly matches. Both teams are part of the U21 European Championship qualification, so understanding how they've been playing in recent fixtures can give us an idea of their current form. Scotland U21 tends to adopt a balanced approach, with an emphasis on strong defensive organization and quick transitions. They often play with width and try to exploit the pace of their wingers and fullbacks. If they dominate possession, their ability to break down deep blocks will be crucial. Bulgaria U21 tends to be more reactive in style, often looking to hit teams on the counter-attack. If they can stay compact defensively and frustrate Scotland, they might be able to spring surprise counter-attacks, especially if they have pace up front.
