Mason, who has played four Under-21s international games, went on to reveal how he found out he’d made it into Southgate’s reckoning for the first games since the coronavirus pandemic.
“I got the phone call, I was at home with my dad,” said Greenwood.
“I was over the moon; I was excited and I couldn’t wait to be here. The manager rang me so obviously it’s good to get the call off him and speak to him about it and come to St George’s.
“He told me about my selection, which I was over the moon with, and [we spoke] about my season with United as well.
“[My dad] was buzzing for me but he’s level-headed so he kept me down really. He’s just excited for me, my whole family was. It’s a dream come true, like I said before, it’s good news.”
