The 24-year-old was pictured training with the Celtic first team on Monday afternoon.
Since the departure of Virgil van Dijk over the summer, Celtic have endured tough times defensively. Most of those have come in Europe but the struggles of some of their defenders have transcended into domestic duty.
Tyler Blackett, Dedryck Boyata, Jozo Simunovic, Efe Ambrose and more... none could be said to have had faultless seasons.
But that's where Eric Sviatchenko should come in. The Danish centre-back has been brought to Celtic this January to bolster their back line and, as well as adding quality, he is adding further competition for places.
Ronny Deila will no doubt hope that extra competition kicks some of his other defenders into gear. The domestic treble is still on for Celtic and it's unclear as to how some of the Norwegian's critics will receive him if that feat is achieved.
Sviatchenko will aim to help his side across the three Scottish trophies and he was pictured in first-team training on Monday afternoon as the Bhoys practiced in the snow.
The 24-year-old also shared a warm embrace with assistant manager John Collins as he enjoyed his first session with his new team-mates. Can Sviatchenko be a hit at Celtic?
