Bale's goals added to Karim Benzema's second-half opener, which came on the first of two costly errors by Liverpool goalkeeper Loris Karius. Sadio Mane equalised for the Reds, who lost star forward Mohamed Salah to injury in the first half after a clash with Real skipper Sergio Ramos.
A fourth triumph in the last five seasons made Real the first side since Bayern Munich in the 1970s to win the trophy three times in a row.
Miracle Goal Proves Bale Should Get More Chances
Play top players, and good things happen. Shocker. It's hardly rocket science, yet Real so often neglect to apply this simple rule of thumb to Bale.
Injuries have played a part, but Bale again found himself on the bench for a big match on manager Zinedine Zidane's watch. Common sense prevailed, however, after Isco floundered playing in support of Benzema and Cristiano Ronaldo.
Bale entered the fray in the 61st minute and needed just three minutes to show he doesn't belong in Ronaldo's shadow. He produced an almost inch-perfect recreation of the latter's overhead-kick goal in the first leg of the quarter-finals against Juventus:
Yahoo Sport Uk's Andrew Gaffney noted how Bale has risen to the occasion since moving to the Spanish capital in 2013:
There was a hefty element of fortune about Bale's second, with Karius offering another helping hand. Even so, Bale has done more than enough to cement himself as one of the catalysts for Real's recent stranglehold on this trophy.
Karius Errors a Reminder Liverpool Must Sign a Goalkeeper
Liverpool manager Jurgen Klopp can't avoid spending big money on a goalkeeper during this summer's transfer window. Karius gifted Los Blancos the lead six minutes after break, all the evidence Klopp needed to make a change between the sticks.
The German had handed Real the lead when he tried to throw the ball out but instead threw it onto the outstretched foot of Benzema.
Not surprisingly, many were quick to express both astonishment and amusement at Karius' gaffe:
Unfortunately for the Premier League side, it was far from the final calamity by Karius. He was rooted to the spot and slow to react to Bale's airborne heroics, while he also swatted the Welshman's straight shot into the net for Real's third.
Afterwards, the 24-year-old was understandably distraught, per Henry Winter of the Times:
While it's near impossible not to have some sympathy for Karius, his sorrow can't hide the fact Liverpool need a significant upgrade at such a key position.
Sports Illustrated's Grant Wahl had a few suggestions about stoppers who would be improvements for the Reds:
Based on the shaky form of Karius and Simon Mignolet, it's a price they can't risk not paying.
Ramos Cast as Villain Again After Salah Injury Leaves WC Hopes in Doubt
Liverpool started brightly but simply weren't the same once Salah was substituted after just 31 minutes. The prolific Egypt international appeared to injure his shoulder after tangling with Ramos in the 25th minute.
Not everybody was impressed by Ramos' effort to stop Salah in full flow:
While the initial challenge resembled something more akin to a coming together, Ramos was soon cast in the role of villain:
Naturally, Liverpool supporters booed the defender's every touch thereafter, while Andrew Downie of Reuters questioned the 32-year-old's rough playing style:
This is hardly the first time Ramos has generated controversy. In December, he broke La Liga's record for red cards when he was dismissed against Athletic Bilbao.
Aside from Ramos' intent, the bigger question may be what the injury means for Salah's hopes of playing at the 2018 FIFA World Cup in Russia next month. Klopp confirmed afterwards there is a chance Salah, who needs an X-ray could miss this summer's tournament, per BBC Sport: "Yes. It's unbelievable. It's something with the shoulder obviously."
The injury was serious enough for him to leave the pitch in tears, likely a response to having to miss out on his chance to shine on such a big stage to cap a phenomenal first season at Liverpool.
Recruiting a goalkeeper and fortifying the defence remain priorities for Klopp, while Zidane and Real should focus on making Bale feel wanted.
