Cristiano Ronaldo announced his retirement from international football on Thursday. It brought down the curtain on a 23-year career with the Portugal national team. Ronaldo made his debut against Kazakhstan in August 2003. Since then, he has amassed 146 goals in 234 appearances – both world records – and won multiple Uefa Nations Leagues as well as the 2016 European Championship. It wasn't the way he would have wanted to end it.
