Odin Thiago Holm has confidently strutted his stuff on and off the pitch, telling Aberdeen star Slobodan Rubezic to 'sit down' on social media.
The first new signing of Brendan Rodgers' second era in Glasgow got a taste of Scottish Premiership action off the bench at Pittodrie as Celtic made it two wins from two thanks to goals from Liel Abada, Kyogo and Matt O'Riley.
Holm impressed the Irishman in the final stages of the enthralling clash in the North East, as Celtic saw the disappointment of losing Reo Hatate to injury despite the Japanese playmaker coming off the bench at half time only to hobble off twenty minutes later.
And it was a feisty affair between both sides but the 20-year-old took to social media following the game to share a picture of him steaming by the new Dons defender, who was left on his backside in the process.
