Costa Rica coach Alexandre Guimaraes has hinted defeat in their World Cup clash against Poland could cost him his job.

The Central Americans lost their first two games to Germany and Ecuador and Guimaraes realises that although there is nothing to play for in the final game, leaving Germany with no points could result in the axe.

Asked if the game on Tuesday would be his last, he told reporters: "I can't say until we have played. Then we will carry out a detailed analysis.

"I am responsible for all the decisions made. If these games didn't ultimately turn out way they could have, I will ultimately be responsible."
