Celtic boss Ange Postecoglou has exited isolation shortly before holding key talks with Dominic McKay in London.
While the Hoops stars who are not on international duty returned to Lennoxtown today, Postecoglou was in the English capital with new Celtic chief executive McKay.
The squad is in need of a massive overhaul following the trophyless season last term and with the likes of Odsonne Edouard and Kristoffer Ajer in the final year of their contracts.
Postecoglou has now completed the required initial period of quarantine having flow in from Japan after leaving the Yokohama F Marinos.
The club note that this in line with the UK Government Test to Release scheme in England rather than Scottish Government protocols.
With the likes of Callum McGregor, Ryan Christie and David Turnbull in the Scotland squad at UEFA Euro 2020, the former Australia boss will also take in the clash with the Auld Enemy at Wembley.
He will then arrive in Glasgow and at Lennoxtown next week to meet the squad face to face for the first time.
The squad are also set to head to Wales for a training camp on July 5.
The gaffer's first games in charge will come in friendly games against Preston and West Ham before the crucial Champions League qualifier against FC Midtjylland.
