Casillas' birthday message to Arconada: If you want to be a goalkeeper, you have to eat sardines LaLiga He told an anecdote from his childhood

Several Spanish goalkeepers looked up to Luis Miguel Arconada, who was also the idol of a young Iker Casillas.

The Porto shot-stopper revealed, through a birthday post on social media, an anecdote about how his mother used Arconada as an example to make young Iker eat fish.

"I remember sitting down to eat at the table and I would be 4-5 years old," Casillas wrote on Instagram.

"My mother had made a salad and some sardines for dinner.

"I didn't like fish that much at that age, but still have it in my head: 'If you want to be a goalkeeper, you have to eat sardines. I've talked to Arconada's mum and that's what he eats to jump a lot for the ball.'

"Obviously, my mother had never talked in her life with Arconada's mother.

"Happy birthday Arconada."

"He hablado con la mamá de Arconada y eso es lo que come para saltar mucho a por la pelota. Obviamente, mi madre no habló en su vida con la mamá de Arconada. #felicidades", escribió Casillas en un mensaje que se ha hecho viral en las redes por se una felicitación de lo más original y que cuenta una historia con su madre cuando era un niño.
