Zinedine Zidane's side ran out 6-0 winners, and if Bale can contribute in similar fashion to the final league game of the season against Villarreal, the Frenchman might have to deal with a selection headache heading into the Champions League showcase in Kiev.
Gareth Bale opened the scoring after 13 minutes for the home side when he beat the offside trap to race on to a Luka Modric through-ball, charging towards goal and drilling a low strike from the edge of the box.
His second on the half-hour mark saw him dash to the byline before tucking the ball to one side of a defender and then unleashing a sharp left-footed drive into the corner of the net.
Wales forward Bale has now scored four goals in four games - a form that boosts his chances of featuring in the UEFA Champions League final against Liverpool on May 26.
Just two minutes later, Isco got his name on the scores sheet after benefiting from a Toni Kroos' assist in the 32nd minute to increase the Galacticos lead to 3-0 before half time. Today was the last game at the Bernabéu and we did all we could to play well and win it.
Atletico goalkeeper Jan Oblak also saved a late penalty from Faycal Fajr as Diego Simeone's men warmed up for the Europa League final against Marseille on Thursday morning (Singapore time) by denting Getafe's hopes of playing continental football next season. "They are a team that work well at the tactical level", said the Argentine.
