He was hailed as the missing piece for Los Merengues after joining from Tottenham Hotspur; however, he was nothing short of an unmitigated disaster early in his tenure. Then, one defining moment altered his perception in the Spanish capital forever.

No, we're not talking about Gareth Bale.

Not yet at least.

Cristiano Ronaldo would then bury his former club just three minutes later.

One defining moment transformed Luka Modric from the worst signing of the season to a permanent fixture in the club's midfield. In a deeper and less attacking role this season, the Croatian has six assists and a passing accuracy that ranks him No. 8 in the league (89 percent).

Gareth Bale, like Luka Modric, underwent a metamorphosis of his own in the Copa del Rey final.

The $132 million man had a modicum of success since joining Madrid in the summer transfer window, scoring 19 goals across all competitions. That number, as impactful as it sounds, was utterly useless for the club. A transfer fee of his magnitude isn't paid to have a modest impact against the likes of Sevilla nor Rayo Vallecano. It's paid to carry a weighted significance against the likes of Atlètico Madrid and Barcelona.

Unfortunately for Real Madrid, Bale was rather insignificant in his confrontations with the Spanish elite. The Welshman had zero goals and one assist in five previous confrontations, but that statistic is no more.

For the first time in his young career, Bale had a defining moment in the white shirt.

His match-winner against Barcelona in the Copa del Rey final showcased every bit of the raw pace and power he possesses. It was even enough to leave his teammate Xabi Alonso amazed (h/t to the Guardian). "The goal was incredible, I don't think I've seen anything like it," Alonso said.

"It looked like the ball was going out and he was under pressure. He ran off the pitch to keep it in," he added.

"It was just amazing."

With the first chapter of his Real Madrid career in the books, Bale will now look to write the next one. Except this time, it'll be written without the pressures of a $132 million price tag weighing on his shoulders.
