Celtic suffered a shocking 1-0 defeat by the Gibraltar minnows.
Quoted by BBC Sport, Celtic defender Erik Sviatchenko is "100% sure" that the Hoops will overturn their 1-0 first-leg deficit by Lincoln Red Imps and reach the third qualifying round of the Champions League.
Brendan Rodgers's Celtic reign got off to an embarrassing start in Gibraltar on Tuesday night as Lee Casciaro - a military policeman away from football - netted a 48th-minute winner to seal a famous victory for the semi-professional club.
Both sides do it all again at Parkhead for the second leg next Wednesday, but Sviatchenko is pretty certain that the Bhoys will atone for last night's humiliation and move a step closer to the group stages.
He said via BBC Sport: "We know that Lincoln are a team that can play football and would give everything. We knew it would be a tough game but I'm 100% sure we will go through."
Last night's defeat was a massive surprise, but losing the tie would be almost unfathomable for Celtic fans in the grand scheme of things.
Red Imps are clearly a better side than everybody imagined, but Rodgers's side will be ready for them next week.
Individually, there no comparison between the Celtic boys and Lincoln's squad, but it is a team sport and the minnows will hope their team spirit continues to compensate for a lack of single talent in Glasgow next week.
