The 61-year-old coach has admitted that the former Real Madrid striker could feature in Poland and Ukraine, adding that he is still waiting for David Villa to fully recover
The 34-year-old has been in stunning form at the Bundesliga club, with 20 goals in 43 competitive appearances this term.
It has been suggested that Raul, who has not featured for Spain since 2006, could make his country's Euro 2012 squad, and Del Bosque was cryptic when asked about that possibility.
"He could potentially be called up," Del Bosque told reporters.
The 61-year-old coach then admitted that he is still unsure whether he will be able to count on David Villa for the tournament as the Barcelona striker is still recovering from a tibia fracture.
"It is our wish to have him at Euro 2012, but he is still in doubt," Del Bosque explained.
"We will wait as long as possible."
Spain will take on Italy, Croatia and Republic of Ireland in the Euro group stage.
