I have the usual Celtic tendency to cheer anyone who is playing against England. And also I enjoyed the hospitality of the Government of Croatia at a very fine embassy reception in Tervuren immediately before the match. But to be perfectly honest, England played better and Croatia deserved to lose.
Not an omission as such, but worth a mention: (spoilers for Her Final Flight)
Her Final Flight has a 6th Doctor/Peri reunion. While it turns out not to be real, it’s still somewhat noteworthy for being the only time both Colin and Nicola played out such a scene together.
