Celtic are due to meet Ibrox side Glasgow Rangers at Hampden Park later this afternoon.
Pierre Van Hooijdonk has wished Celtic good luck on Twitter, ahead of their Scottish League Cup match against Glasgow Rangers later today.
Celtic and Rangers are due to meet in the semi-final of the cup competition, in what will be the second Old-Firm derby of the season.
When Celtic and Rangers met last month, Brendan Rodgers’ side ran out 5-1 winners.
And Van Hooijdonk, who represented Celtic during his playing days, is hoping for a similar result this time around.
Celtic go into the match as the heavy favourites, as they have made a highly impressive start under Brendan Rodgers’ stewardship.
The Bhoys are currently unbeaten in domestic action, but they do head into the match on the back of a defeat against Borussia Monchengladbach in Champions League action.
Rangers, meanwhile, have improved since defeat in the Old-Firm derby. The Light Blues’ new players appear to be starting to settle in at Ibrox, and Mark Warburton’s men have won three of their last four matches.
