Cavan Sullivan is fast becoming one of American football's most exciting prospects. The 16-year-old made his senior USA debut on Saturday and delivered a display that underlined why Manchester City moved to secure his signature, according to BBC News.

Sullivan, who plays for Philadelphia Union, has a deal in place that will see him join City's ranks once he turns 18, with the Premier League champions having tracked him closely as one of the brightest young talents to emerge from MLS.

His performance for the national team was seen as further proof of his readiness to compete at a higher level, with the BBC noting that it showcased the qualities that first attracted City's scouts. At just 16, Sullivan's rise has been rapid, and his senior international bow marks another milestone in what is shaping up to be a closely watched career on both sides of the Atlantic.
