Belgium boosted their hopes of finishing second in Euro 2012 qualifying Group A with a convincing win at home to Azerbaijan.
Jan Vertonghen gave the hosts an early advantage only for Ruslan Abishov to level.
Belgium were carving out plenty of chances, though, and Timmy Simons put them back in front from the penalty spot before Nacer Chadli made it 3-1 at half-time.
And Jelle Vossen put the seal on victory with a fourth in the 74th minute.
The win moved Belgium a point clear of third-placed Turkey in the group, with Germany comfortably on course to finish top.
