Kasper Hamalainen gave Finland a surprise lead against Belgium, but Romelu Lukaku's 89th-minute effort staved off a shock defeat.
Romelu Lukaku came off the bench to earn Belgium a last-gasp 1-1 draw with Finland at the King Baudouin Stadium on Wednesday.
Having scored in the 2-1 victory over Switzerland on Saturday, Lukaku was rested in Brussels, with Michy Batshuayi and Divock Origi handed starting berths in attack.
Marseille striker Batshuayi rattled the post with a first-half header, but Belgium went into the break level despite dominating the first half.
With the likes of Vincent Kompany and Nicolas Lombaerts out through injury, Marc Wilmots' defensive concerns were added to when Kasper Hamalainen pounced on Thomas Vermaelen's static positioning to guide the ball between the legs of Thibaut Courtois.
