Reyna thanks Aguero for 'amazing' moment with late brother

The Borussia Dortmund star and son of former Manchester City and Rangers regular Claudio, fondly remembers the Argentine's most famous moment in a City shirt - the title winning goal against QPR in 2012.

A moment that will live long in the memory for City fans provides an equally joyous but deeper meaning to Reyna, who opened up on how he celebrated the dramatic title-clinching goal to the Players' Tribune.

"One of these days I really need to say thank you to Sergio Aguero," said Reyna.

"For a long time I have been like, I need to play against this guy, just so that I can talk to him.

"Not just because my grandfather is Argentine, or because Sergio is one of my family's favourite players, or because at the World Cup two years ago we all sat in front of the TV rooting for Argentina.

"Nah. I have a story to tell him. Many years ago Sergio scored a goal that gave me one of the happiest moments of my life.

"To understand why, you need to know about my older brother, Jack."

The 20-year-old continued: "Jack was my hero when I was a kid. Some people think that my dad, Claudio, made me a good player, since he was a pro himself. Sure, he gave me great advice and some pretty good genes.

"But when I was growing up in Manchester, where Dad was playing for Manchester City, the one who always played with me in the backyard was Jack.

"We had the old Samba goals, you know? One-on-one, nowhere to hide. I was four years old and Jack was three years older, so he would sometimes let me win by letting a few shots slip under his foot. Most of the time, though, Jack would make sure I lost. And I'd get angry. I'd kick him, bite him, fight him. Then I'd cry and run to my mum, Danielle. Those games made me grow up a lot, and Dad will tell you the same thing. My competitiveness, my feistiness, all that came from trying to beat Jack."

"He was the perfect brother. I was always a shy kid, so he would include me in whatever he was doing with his friends, which meant that I got used to playing against kids who were several years older. That gave me confidence. When I wasn't around, he'd say nice things about me. When he realized that I was going to be better than he was, he pushed me to become the best I could possibly be. And if I had played a good game, he would be the first person to call me to tell how well I had played.

"In 2007, our family moved to New York, where Dad played for the New York Red Bulls. In the summer of 2010, Jack was diagnosed with brain cancer. He was 11 years old. At one point it looked like he was going to make it, but in December 2011, the doctors discovered that the tumor had come back. Shortly after that, when we went on a vacation to Mexico, Jack started to get sick and put on pounds because of the chemotherapy. He could still walk and swim, but he got tired very quickly. That was when I figured out that this could end in a very bad way.

"Over the next few months I did everything I could to help him. I had to grow up fast. He couldn't pull himself up. There was a point where he had to wear diapers. I learned how to microwave food, I did the dishes, stuff like that. I also hung out a lot with my younger brother, Joah-Mikel, and my younger sister, Carolina, who were having a tough time, too. I just wanted to make my family happy, and to make Jack happy, of course. All of us did, especially when we knew that he only had a few months left to live. Every night at the dinner table we would tell each other stories and laugh. Every night. Somehow, even in such a devastating situation, we managed to have some fun.

"One day in May 2012, when Jack was 13, we gathered in the living room to watch the final day of the Premier League. I think even my grandparents were there. We are all big City fans, because Dad played there, and on that particular day City could win its first league title in 44 years by beating Queens Park Rangers at home. If City didn't win, we had to hope that Manchester United, which was behind City only on goal differential, didn't win either.

"We were all pretty positive that City was going to beat QPR, one of the smaller teams in the league. When City scored in the first half, the win, and the title, seemed like a formality.

"But QPR turned the game around and took the lead in the second half. Since United was winning, City needed two goals. In our living room nobody was smiling anymore. I felt bad for Jack. He was so sick at that time that he couldn't walk or talk. Now he wasn't going to see City win the league either.

"Two minutes into stoppage time Edin Džeko equalized. That gave us some hope, even though the game was almost over. Two minutes later Agüero scored the winner.

2You've seen the goal. You've heard the commentary.

"AGÜEROOOOOOO!!"

"We went crazy in the living room. We were jumping around, shouting and celebrating and hugging each other. A first league title in 44 years! Won in the most incredible manner. We looked at each other in disbelief.

"Suddenly we heard someone gasping for air. It was Jack. He was rolling around on the floor, which came out of nowhere because he barely had any energy left in his body. We got very concerned. For 20 seconds it looked like he couldn't breathe.

"Then, slowly, Jack broke into a smile and began to laugh. We realized that he was celebrating the goal. He was just as happy as we were.
