Luis Nani was 12 years old when he first became aware of Cristiano Ronaldo, and his incredible will to win.
Nani was in Lisbon for a trial with Sporting C.P., where a teenage Ronaldo was already making a name for himself.
Nani quickly realised why; during a youth-team game at Sporting's training complex, Ronaldo was left in tears on the sidelines after the referee had decided against awarding him a free-kick, thus allowing the opposition to race down the other end of the pitch and score.
Ronaldo's coach went over to him as he sat feeling sorry for himself and said: “Come on, you can’t do that! You need to keep pushing. Sometimes things will happen."
Ronaldo re-entered the field of play, immediately got on the end of a cross and took two touches before backheeling the ball in the net.
Nani was awestruck.
“Seeing Cristiano that day, and how behaved, made me realise why he was so good,” Nani tells Goal in an exclusive interview. “Even at that time, you could see he was something else compared to the other players.
“Everyone was saying he'd be the best, so I started to look at him and thought to myself: 'I need to improve myself'.
"At that age I knew I was good but I was not at that level, so I started focusing on the best players like him. I started pushing myself more and, in a month, I was able to see that I had improved so fast.”
Nani realised his dream of playing for Sporting when he made his senior debut in 2005 but only spent two seasons in Portugal before securing a €25.5 million (£21.8m/$30.1m) transfer to Manchester United.
His determination to try to emulate Ronaldo's winning mentality had earned him the chance to join his compatriot at Old Trafford. “It was beautiful,” Nani enthuses.
And they didn't just share a dressing room together. Nani moved in with Ronaldo and another Portuguese speaker, Brazilian midfielder Anderson.
“It was great for us," he reveals. "We were three young players who like to compete every single day and we had everything available to us at home to enjoy: swimming, ping pong, tennis, and that was making us better every single day. It was perfect!"
While they had a great relationship off the pitch, Ronaldo’s imperious form kept Nani on the periphery for a couple of seasons. In his maiden campaign, he made 16 league starts but in his second, just seven.
Still, Nani never held any hard feelings towards his good friend. Quite the opposite, in fact.
“It was great," he explains. "When you have a player like him in your team, you’re not afraid of anything or any team. I think that’s the greatest feeling you can have when you play with him.
“You’re always ready, always confident you can win and he gave that to us every single season."
At the end of Nani's first year in Manchester, United won the Premier League and FA Cup double, an achievement he will never forget – not least because he wasn't fully prepared for United's title celebrations on the final day of the season.
“I wasn’t in the team against Wigan," the 34-year-old recalls, "so I was sat in the stands. When Ryan Giggs’ goal went in, they sent me to the dressing room to get changed for the celebrations.
“But I didn’t have any boots. So, I was scrambling around looking for some boots and I had to put Owen Hargreaves' on! They were a bit big for me but I wasn’t bothered. I just wanted to celebrate with the team.”
That was just the beginning for Nani, though – the first of four league titles he would win under Sir Alex Ferguson.
When Ronaldo left for Real Madrid in 2009, Nani emerged out of his shadow and became a regular in the team down the right wing, scoring some spectacular goals in the process. But what was his favourite?
“I think the one against Chelsea at home (in 2011),” he muses. “It was a difficult game, against a strong team in front of our fans. It was a great strike against a good goalkeeper (Petr Cech) and it’s not easy to score a goal like that against him."
That goal was, of course, quickly followed by his trademark back flip celebration. There were subsequent suggestions that Ferguson didn't approve of his acrobatics but Nani insists it was never discussed.
“There were some rumours in the club that he thought that it was a problem but I never stopped,” he said. "The manager never came to me and said anything about it.
“One game, I scored a goal and I didn’t do it, but that was because I had a pain in my foot and I couldn’t do the back flip! As soon as I got better, I did it again.”
Nowadays, the celebrations are more muted, with Nani joking that he is not 18 anymore.
But he retains his capacity for a spectacular strike. Just like Ronaldo, he is still going strong in his mid-30s. Indeed, he is presently tearing up MLS as captain of Orlando City.
This season, he has played 16 league games, scored nine goals and registered six assists.
“I think it’s been a great year for me and my team,” he said. “The team is much stronger and we’ve been performing very well against strong teams in MLS and getting good results. For me, especially, this season has been my best season here. I feel very confident.”
Nani is also revelling in his role of leader. He names Rio Ferdinand, Nemanja Vidic, Giggs and Patrice Evra as former team-mates he learned a lot from during his time at Old Trafford and that has moulded him into the captain he is today.
“The experience of different challenges over the years at different clubs, you take a little bit from each experience you have in your career and put it all together. That’s what helps me lead the team,” Nani says.
“I have respect from the club and all my team-mates, and I feel at home. The responsibility I have is good for me to give me the motivation I need every single day to continue to work hard and improve and make sure I can help the players around me develop.”
Just as Ronaldo helped him improve at the very beginning of his career, he is now passing his winning mentality to those around him.
And he hasn’t given up hope that one day he’ll be reunited with his friend. It won’t be this summer as Ronaldo is heading back to Old Trafford, but Nani isn't ruling anything out.
“The future is in God’s hands but maybe it’s possible, you never know,” Nani said about Ronaldo joining him in MLS.
But how long can they both keep going? Nani is 35 in a couple of months and Ronaldo turns 37 in February.
“I just keep going and keep working and try to maintain my health and do my best every single season,” Nani adds. "The focus keeps me going and the experience of how to treat yourself, you need to keep motivated to work every single day and maintain health.
"That’s the secret: if you’re healthy you can continue to work.”
