James Justin's season began on 4th September when he was an unused sub for England U21s. He's started three and been on the bench three times in their six matches since then.
In addition, this is James Justin's 16th start and 17th appearance for City out of 18 games this season (he came on as sub againt Zohya at home and was an unused sub against Arsenal in the League Cup).
So today is the 24th game he's either started (19) or been sub (5) since Sept 4th (97 days). He also started all 10 matches we played between 20th June and 26th July.
In total, he has started 29 of the last 34 matches played by City or England U21s and been sub for the rest.
