McLeod & Lambert, the Dortmund duo
Celtic and Borussia Dortmund are set to meet for just the third time on Tuesday.
The pair have met only twice in old Uefa Cup ties.
The first of those in 1987 featured a quick-fire return to Celtic Park for the great Murdo MacLeod, who enjoyed his time in Germany almost as much as they enjoyed having him there.
A decade later, a successful future Celtic captain Paul Lambert hoisted the European Cup above his head in Dortmund colours as they beat a fabulous Juventus side in Munich to lift the trophy for the only time in the club's history.
Dortmund and Celtic are intrinsically linked by those two as the clubs prepare to do battle in the biggest tournament of them all, with Rodgers and his players eyeing up history.
