Poland coach Pawel Janas was left with a mountain of problems after his side's latest World Cup warm-up game ended in a 2-1 home defeat by Colombia.

A last-minute Ireneusz Jelen goal was all the Poles had to show for their efforts, with keeper Tomasz Kuszczak coming under fire for allowing opposite number Luis Enrique Martinez to score with a long kick downfield.

Janas said afterwards: "It's not yet time to talk about a crisis because we are still at the preparation stage.

"This match was not a success and I do feel some concern.

"There were moments where we did not control the situation on the pitch and we did not carry out the tactics we had set ourselves.

"In particular I was not satisfied with the defence.

"The players lack dynamism and pace, but we have another nine days until the finals and we will work on this in Germany."
