The former Real star is advising Bale to use the weight of the famously hard-to-please home crowd's frustrations to improve his game and prove them wrong.
25-year-old Bale has experienced a tough second campaign at the Santiago Bernabeu, receiving boos from the home crowd despite a healthy return of 17 goals in 44 appearances and scoring in the FIFA World Club Final against San Lorenzo, the third major final he has notched in.
But with Real sitting in second place in La Liga, just two points behind leaders Barcelona, the Welsh wide man has had to endure criticism from the home fans as they seek a first Spanish title win since 2011-12.
Some Real fans may feel the criticism is justified given Bale's patchy form overall judged against his world record fee - a reported £85 million in 2013 (per the BBC) - and the Brazilian ex-Real forward Kaka has commented that Bale should be big enough to use the criticism to his advantage.
Speaking to Sky Sports, Kaka said: “I’ve never played with Bale, but I would say to him to use the pressure to help himself grow his motivation and confidence. In Madrid, pressure is normal. It’s not just with him, it’s with everybody. Even Cristiano [Ronaldo], who has won two Ballon d’Or’s with Real Madrid, receives whistles from the Bernabeu."
Kaka, who spent four years at the Bernabeu between 2009 and 2013 making 120 appearances, returned to AC Milan after an injury-hit spell at Real where he was still a popular player with the crowd, and he now plays for MLS franchise Orlando City in the USA.
Bale, meanwhile, is having to contend with constant speculation on his future, with reports linking him with a return to one of the top clubs in the Premier League (per the Daily Mail). It is this speculation that is perhaps unsettling the former Tottenham star, but Kaka stressed that the pressure of the price tag and playing for Real - and the criticism that goes with it - should spur him on.
"He needs to use this opportunity to get stronger," said Kaka "That is my advice for Bale.”
