Colombia boss Jose Pekerman has dedicated his side's resounding 3-0 win over Poland to Carlos Sanchez after the defender received death threats following his red card against Japan.

Sanchez was sent off inside three minutes of Colombia's opening World Cup match, which they went on to lose 2-1, prompting the defender to receive a number of death threats.

But Pekerman has leapt to his player's defence after the reaction 'deeply affected' Sanchez, who could only watch their win against Poland from the sidelines.

'He's had a hard time. We want to share this win with him,' said Pekerman. 'The whole squad feels the same.'

Police are investigating the threats against Sanchez, which were particularly chilling given the murder of Colombian defender Andres Escobar, 10 days after scoring an own goal against USA in the 1994 World Cup.

It was a demonstration of unity from the Colombia squad as they dedicated the win to Sanchez, while Pekerman also hit out at those who felt the need to make violent threats.

'We received certain information, but I can't confirm anything,' Pekerman added.

'The player was deeply affected, and I think we all understand football really is something else.

'These things shouldn't even be said lightly. Whether it's confirmed or not, this is something that is extremely painful.'

Next Colombia will face Senegal in the final round of group games, with Japan up against the already eliminated Poland.

A win over Senegal would ensure Colombia progress to the knockout phase, but anything less and they are in serious danger of being eliminated.
