Ahead of this evening's Champions League play off at Ibrox, PSV Eindhoven's top brass, key sponsors and corporate guests are spending the day at Celtic Park.
Before facing Rangers tonight, the special guests have made their way to Parkhead for a specially organised tour of the stadium. The PSV VIPs were given the lowdown on all things Celtic by celebrity tour guide Jan Vennegoor of Hesselink.
The former Dutch baller spent time with both sides during his playing days, enjoying two spells in Eindhoven on either side of a three year stint in Glasgow's east end. And he remains a hero among Celtic supporters, with a certain game during the 2007/08 campaign a particularly fond memory for the Parkhead faithful. Vennegoor netted a vital goal for Gordon Strachan's side who pulled off a truly remarkable comeback to keep hold of the league trophy for a third season in a row.
