Raul has scored his 400th career goal as Schalke recorded a 4-0 win over Wolfsburg in the Bundesliga.
The Spanish veteran tapped in from close range early in the first half to give his side the lead.
The 34-year-old is also the all-time leading goalscorer for former club Real Madrid, and the Champions League's all-time leading marksman.
Raul joined Schalke in 2010 after 16 years at the Santiago Bernabeu.
