Poland head coach Adam Nawalka said that his side was well-prepared physically and was not affected by the hot weather in Monday's (AEST) 3-0 defeat to Colombia in Kazan.
Colombia opened the scoring late in the first half through defender Yerry Mina. Radamel Falcao doubled Colombia's lead in the 70th minute with a clinical finish and Juan Cuadrado made the game safe with 15 minutes to go.
“I don’t think that the heat affected us. Physically we were well-prepared, but our opponent was better. That is why we couldn’t match them,” Nawalka said post-match.
Poland have lost both of their group matches, going down to Senegal 2-1 in their first match of the World Cup and are bottom of Group H with zero points.
The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the matches being played in 11 cities across Russia.
