The Bhoys shot stopper saved a penalty and generally impressed during his side's 4-1 win over Eibar.
He's a 'keeper, this one. Indeed, Logan Bailly produced a memorable Celtic debut on Saturday afternoon against Eibar - even if it was just a friendly.
Having arrived at Parkhead this summer, the 29-year-old Belgian stepped in ably for the Hoops in Spain, no doubt giving Ronny Deila encouragement that he can provide the requisite cover and competition for outright no.1 Craig Gordon.
No one can quite challenge Gordon at present, such is the goalkeeper's form and even status at Celtic right now. But depth and, once again, competition are vital for a club looking to compete on three domestic fronts - and the Champions League.
Bailly's display was therefore rather encouraging, as the stopper denied a penalty and produced a number of other saves under pressure. Efe Ambrose netted for Celtic, while last season's top scorer Leigh Griffiths bagged yet another hat-trick for the Bhoys. Overall, it was a very good run out indeed.
Especially for debutant Bailly, with the 29-year-old impressing supporters on social media. Here's a selection of the Celtic reaction to his first game with the Hoops on Twitter...
