Professional services company Deloitte has renewed its partnership with the Polish Football Association (PZPN).
Deloitte will retain its position as an official partner of the PZPN until 2020.
The partnership is designed to maximise the potential of amateur football in Poland.
The new deal has been signed to coincide with the start of the Fifa World Cup national team tournament in Russia, where Poland has been drawn alongside Japan, Senegal and Colombia in Group H. Poland's first match is against Senegal next Tuesday.
