FIFA World Cup: Playing for different countries doesn't stop Williams brothers from sharing advice - Doha (Qatar) News

Nico is representing Spain, while Inaki formed part of the Ghana squad, opting to play for his parents' homeland.

Although Inaki is now enjoying a week's holiday before returning to training with Athletic Club Bilbao after Ghana's elimination, Nico is still in Qatar preparing for Spain's last-16 tie with Morocco on Tuesday.

The young winger started in Spain's 2-1 defeat to Japan last Thursday, making his sixth appearance, but his first start, before being substituted as Spain looked to fight back from a goal down.

Speaking on Spanish radio on Monday morning, he explained how his older brother gave him some post-game pointers, despite forming part of a rival squad.

"On our day off, I was with some friends and my family and my brother corrected a few things that I didn't do well (against Japan)," said Nico.

"He didn't tell me off, but he did correct a few things that I can improve. He saw them from a different perspective to me and he is more experienced, so it was easier," continued Nico.

"Inaki told me that I need to move more for the ball and I was too static out wide. It's not a problem I have at our club (Athletic Club Bilbao). I don't know if it was nerves, but thats what happened," he admitted.

Despite Thursday's disappointment, the 20-year-old admitted that he was enjoying the World Cup experience, reports Xinhua.

"It never entered my head that I would play in the World Cup, it's the best thing that can happen. I'm still a young lad and to get where I have is a matter of pride for myself and my family. Never in my wildest dreams did I think I would be here," Nico admitted.
