Poland star Robert Lewandowski rued his team's errors and their unwillingness to take risks during their 2-1 World Cup loss to Senegal on Tuesday.
An unfortunate Thiago Cionek own goal and a first international strike from M'Baye Niang helped Senegal upset Poland in their Group H clash in Moscow.
While Grzegorz Krychowiak pulled a goal back for Poland in the closing minutes, they were unable to find a second to rescue a point.
Lewandowski said errors and a failure to take risks cost his team, but he vowed they would be better in a crucial clash against Colombia on Sunday.
