It was a huge moment for the team.
Southgate is trying to rebuild England's confidence after the shock of last year's Euro 2016 humiliation by Iceland and said his players' perseverance in the face of improbable odds was a sign that they are on the right path. That's what we've got to show.
Southgate also revealed that he will make changes for Tuesday's friendly against France with John Stones likely to come in for Chris Smalling and Marcus Rashford probably starting on the bench. Maybe the clock runs out but you never ever stop.
It was brilliant for Harry to execute such a goal in the circumstances.
The national side were just moments away from a famous win over England after Leigh Griffith's free-kick double put them 2-1 up in the 90th minute. "It was probably the tallest wall you could put up in European football today and he went round the side, over the top, he is a good character, a wonderful character, odd but wonderful", he said of the Celtic forward.
The draw keeps England top of their group ahead of Slovenia by three points with Scotland back in fourth.
On a sun-kissed Glasgow afternoon, England took the lead in the 70th minute when substitute Alex Oxlade-Chamberlain's left-foot strike beat home goalkeeper Craig Gordon's flimsy attempt at a save.
"I'm sure he'll be disappointed to concede any goal". We had moments where we got into really good positions in the final third and you have got to take the finish.
"I have been involved with Scotland for 40 years now and I can not remember anyone hitting a better free-kick and then coming away and hitting an even better one".
"Then, most importantly for me, heading into injury-time 2-1 down, I don't see anyone sink to their knees, I don't see anyone hit the floor". So these memories will be with me. These guys are giants, they play at a different level to most of us, and they kept coming back. I can't be annoyed. "It's annoying for them to do so much and have a result that could have been one of the best results ever". It's not often they come off, it's special.
