Celtic sealed top spot in Europa League Group E with a comfortable 3-1 home win over Rennes on Thursday.
Neil Lennon's men had already reached the knockout stage after matchday four, but Lazio's victory against Cluj ensured the Hoops will finish at the summit of a European group table for the first time.
Already-eliminated Rennes scarcely looked capable of stalling the hosts and Lewis Morgan and Ryan Christie had the Scottish Premiership champions two up at the break.
Mikey Johnston came off the bench to add a third, before fellow substitute Adrien Hunou grabbed a consolation for Rennes, but Celtic can look forward to a trip to Cluj with little on the line, while domestic title rivals Rangers remain engaged in a tense group-stage tussle.
