The PSV - Feyenoord game on September 17 is a battle between two clubs to become the champion. At the same time it is also a clash between two competitive energy companies; PSV is sponsored by EnergieDirect whilst Rotterdam players have Qurrent on their shirt. Cees van Riel of RSM understands that the amount that football clubs receive for shirt sponsorship is under pressure. "Shirts sponsorship is a flat solution for companies. Yes, you are building brand awareness, but no more", he says.
