Colombia coach Jose Pekerman dedicated a crucial 3-0 World Cup win over Poland to midfielder Carlos Sanchez on Sunday after reports said the midfielder received death threats for his red card against Japan.

Sanchez was suspended for the game at Kazan Arena as Colombia got back in contention for a place in the last 16 and Poland were eliminated, and has had "a very hard time" dealing with the fallout from his third-minute sending-off in the 1-2 defeat to Japan, Pekerman said.

The Espanyol midfielder will be eligible to return to Pekerman's side for the make-or-break last Group H clash with Senegal on Thursday.

Pekerman said he spoke for the whole squad when he dedicated Colombia's victory to the 32-year-old player.

"This victory is dedicated to Carlos Sanchez because he's had a very hard time in the past days. I want, and we want, to share it with him," he said.

"I'm saying this personally, but this is something that is felt throughout the squad."

Although Pekerman refused to confirm the reports, he came close.

It evoked memories of the chilling murder of former Colombia player Andres Escobar, who was killed after his own goal led to defeat to the United States in the 1994 World Cup and Colombia's elimination from the tournament.

Pekerman added: "We received certain information, but I can't confirm anything. The player was deeply affected by this matter.

"It went beyond football. It's a game that we play with a lot of hard work and dedication, but these things should not be taken lightly.

"Whether it's confirmed or not... this is extremely painful."

Colombia's march to the quarterfinals in Brazil four years ago came thanks to James Rodriguez's six-goal tally for 'Los Cafeteros'.

And days after a calf injury restricted him to a half-hour cameo role against Japan, the Bayern Munich midfielder was back to his best in an ultra-offensive line-up that gave Radamel Falcao his long-awaited maiden World Cup goal and Juan Cuadrado Colombia's third of the evening.

Cuadrado teased and frustrated the Polish defence in a positive start to the second half, and after Colombia 'keeper David Ospina bravely denied Robert Lewandowski when he latched on to a dangerous long ball, Colombia turned up the heat.

When right-back Santiago Arias found Juan Quintero, the midfielder sliced Poland's defence apart with a low pass that found Falcao on the run before he coolly beat Wojciech Szczesny down low with the outside of his right boot.

Five minutes later, Rodriguez produced arguably the assist of the night, drawing several Polish players on the left flank before somehow finding Cuadrado on the run with a superb cross-field pass that the pacey winger tucked away.

Disappointing Poland became the first European side eliminated from the tournament and the normally prolific Lewandowski failed to fire again, but coach Adam Nawalka was stoic in defeat.

"I'm very sorry and very sad about the result, but tomorrow's another day and we have to come to terms with things," he said.
