Although the 31-year-old forward did not travel with the team to Germany for their European encounter, Son remains closely connected to the group.
"Yeah. I mean, he wasn't in contact with me, but he was with the boys, obviously, and yeah, he’s still a big part of it," Postecoglou said. "We discussed whether we should come along, but like I said, I think to give us the best chance of Sonny being available for the semis and beyond, it just made sense that we left him at home. But yeah, I'm sure he was very much part of the group.
"What do they call them, group chats, or whatever they are? They are part of some group. I'm not in any. I just saw him this morning, actually, I just caught him in the hallways as I was coming over, and he's delighted for a number of reasons, and real motivation there to get back as soon as he can."
