Siblings Miko and Alex Eala train under Rafael Nadal amid lockdown

Siblings Miko and Alex Eala have spent the lockdown honing their tennis skills from one of the best to ever pick up a racket: Rafael Nadal.

With tennis season interrupted due to the coronavirus disease 2019 (COVID-19) pandemic, the 19-time Grand Slam champion has the time to personally oversee the training of the athletes in the Rafa Nadal Academy (RNA).

According to Chino Trinidad's report for "24 Oras," Miko and Alex made the most of the opportunity to spend time with the legendary Spaniard.

"He's not cocky, he's not arrogant," said Alex about Nadal. "Especially for all the things he's achieved in his career, it takes a lot of character and personality to be as humble as he is."

Alex made waves after winning the Australian Open Juniors doubles title in January. She is currently ranked fourth in the International Tennis Federation (ITF) juniors' world tennis rankings.

Miko, meanwhile, will be playing Division I tennis at Pennsylvania State University in the United States. 

Asked about the most important lesson he learned while attending RNA, he said it's to treasure the time spent with the people you love.

"The biggest thing I learned siguro is to appreciate everything that you have," Miko said. —MGP, GMA News
