The champions entertain Partick Thistle on Tuesday
Celtic's impressive domestic season has so far seen them go unbeaten in 16 league matches this year.
Brendan Rodgers' side also picked up their first piece of silverware beating Aberdeen 3-0 in the League Cup final last month.
Speaking to the club's official website, Celtic defender Erik Sviatchenko said: “It’s a nice feeling to be on a run when we haven’t lost for 20 games now and it’s important for growing the confidence going into every game, knowing we are difficult to beat, and we will try to continue it, which is the main thing.
“It’s positive, especially for a defender to be unbeaten and it’s something I cherish and something a defender should cherish. We aren’t unbeatable but the feeling of it grows in our mind, and the first place it starts is the belief, which gives us the opportunity to go into the games and win them,” he added.
The Glasgow giants welcome Partick Thistle to Celtic Park on Tuesday night looking to build on their excellent league campaign which has seen them win 15 of their 16 matches with a single draw against Inverness back in September their only domestic blemish.
They currently sit 11 points clear of second place Rangers and have two games in hand.
