An estimated 25,000 supporters are expected to attend Holland's open training session in Krakow tomorrow afternoon.
The Dutch squad arrived at their base in the Polish city yesterday afternoon and underwent their first practice session this morning ahead of Euro 2012.
On Wednesday coach Bert van Marwijk will open the gates for the public to watch him put his side through their paces.
It has been reported that the session will be a light one for the Dutch squad, with Van Marwijk keen not to give away any of his tactics to group opponents Germany, Portugal and Denmark.
