Bellingham opened the scoring at the Etihad on Wednesday night and put in a man of the match display as the Bundesliga side looked to upset the English champions.
But it was not to be for Dortmund, with John Stones and Erling Haaland scoring two late stunners to rescue a win for City.
Nevertheless, 19-year-old Bellingham yet again showed why he is one of the most sought-after midfielders in world football, with the likes of Liverpool, City, Chelsea, Manchester United and Real Madrid reportedly interested in his services.
City manager Guardiola is certainly a fan and was asked what he made of the England international’s skill and maturity for such a young player.
‘I was impressed two seasons ago when he was 17!’ the Spaniard said in his post-match press conference.
‘He’s able to defensively follow [Ilkay] Gundogan or Kevin [De Bruyne] in the pockets and win the duels. The transition is fast, have the sense to get in position in the box for the goal he scored.
‘An exceptional player. I think everyone knows it, not just because the manager of Manchester City is going to tell you.’
During the summer, Bellingham said that he had no intention of leaving Dortmund, claiming he was happy to continue his development in Germany, where he has scored 13 and assisted 18 in 99 games so far.
This was a point he reiterated in his pre-match press conference on Tuesday, saying: ‘The club [Dortmund] have done loads for me and made me feel very welcome since I first came and gave me the opportunities to develop even further.
‘To look past that and into the future would be disrespectful. [A return to England] is not something I am thinking about, to be honest.’
In spite of this, many believe it is only a matter of time before the midfielder, valued upwards of £70million, follows the likes of Haaland and Jadon Sancho from Dortmund to the Premier League.
