The tweet was all about Kwon Hyeok-kyu and Yang Hyun-jun but any video from training sessions has a double meaning.
With just over a minutes of various action shots of players at training most Celtic fans perform a roll call to see who is and who isn’t involved.
Cameron Carter-Vickers was pictured at Glasgow Airport ahead of the training trip to the Algarve but there was no sighting of the defender during the social media releases from the club during their two match trip to Japan.
Little has been known about the pace of rehab following knee surgery at the start of May but the sight of the former Spurs defender out on the grass with his team-mates today looks like a definite step forward.

With two friendly matches to be played before the SPFL opener against Ross County on August 5 the Celtic medical team will be monitoring Carter-Vickers very closely for his reaction to being back out on grass, training, twisting, turning putting pressure on the knee.
If all goes well he could be involved in the matches against Wolves and Athletic Club Bilbao although the signing this week of Maik Nawrocki gives Brendan Rodgers an extra option in central defence.
Tony Ralston was back in training despite missing the matches in Japan but there was no sign of Alistair Johnston.
