Celtic defeated FC Astra 2-1 at Parkhead on matchday three of the Europa League.
Chances were missed at both ends before Stefan Scepovic broke the deadlock in 72 minutes, heading home an Anthony Stokes free-kick via the underside of the bar.
Stefan Johansen lashed home the second goal five minutes later before Gabriel Enache pulled one back for the Romanian side.
Celtic have seven points from nine in Group D, as do Salzburg, who beat Dinamo Zagreb 4-2 tonight. Their next match is away to Astra on Thursday November 6.
