Jude Bellingham's mentality is what separates the Borussia Dortmund midfielder from his peers, according to Pep Guardiola.
Manchester City are in Germany on Tuesday requiring a draw to confirm top spot in the Champions League group stages but are expecting a stern test at the febrile Westfalenstadion.
Bellingham, 19, captained the side for the first time earlier this month and has consistently shone for club and country since leaving Birmingham City two years ago.
'I noticed when he was 17 that it wasn't just the quality - it was the shouting, kicking, going to the referee,' Guardiola said.
