There are not many English footballers who have made an impact on the England team while still not officially an adult. Wayne Rooney and Theo Walcott are the only ones to do so in the modern era, which gives you an idea of the calibre of Jude Bellingham.
Those watching Borussia Dortmund's Champions League victory over Sevilla on Tuesday cannot help but have noticed the growing maturity of the 17-year-old at the heart of the midfield at one of Europe's best sides.
The difference is that while Rooney did his growing up in the full glare of Premier League publicity, famously scoring a last-minute winner against Arsenal when just 16, or in Walcott's case transferring from Southampton to Arsenal at 17, Bellingham is not a player with whom English audiences are overly familiar.
