It's ironic really.
If the England defence had played better and we had been 5-0 up in the 80th minute, I reckon Southgate may have given Mings (and Maddison) a run out with nothing on the line.
But because the defence was so bad and we were in danger of not winning, he wanted to stick with his 'established' players even though they were the ones that screwed it up in the first place.
Ah well, an uninjured Mings is better than a capped Mings
