They looked very happy and inspired on the stands yesterday so yes watching some of the best players showing how good football really can be most likely inspired quite a few Latvian girls.
Not sure why Englishmen are obsessed with the idea of pre-qualifiers in both the men's and women's game. My guess is that is the same kind of arrogance that resulted in Hodgson going on some ****ing sightseeing rather than scouting Iceland in 2016 and the same one that makes every English player horrified when there is a penalty shootout, "oh this is serious stuff I'm gonna shit my pants and go home". The whole "we are too good to play these minnows" is embarrasing. Yes, you are better and yes you may stomp them but you are in no position to try to dictate who are good enough to participate or not.
One of the players Junior works with was on the wrong end of a bit of a thrashing by England recently - pretty much knew it was going to happen due to the gulf in class, but had the opportunity to play at Wembley in a televised game in front of 20k+ when she's used to playing in front of a few hundred - imagine that was quite inspiring.
