Victory would send the Chileans through to the round of 16, while Congo will be hoping to replicate the strong second half display they produced against Austria, where they hit back in style to draw 1-1.
Chile are back to full strength with the return of star striker Alexis Sanchez and defender Hans Martinez after they sat out the Canada match. Chile coach Jose Sulantay said it would be difficult to change a winning team but it seems likely that Sanchez will feature against Congo, who report no injury concerns
This is the first meeting between the two countries at all levels of international football.
"Playing Congo will be completely different for us. We saw their game against Austria live and also the repeat on TV and their players are very strong. Three or four of them have great agility and that's their strength so we will try to deal with this. We are calm now. We have three points already and winning against Congo would put us through to the next round, which will give us another opportunity to keep going even further." Jose Sulantay, Chile coach.
"We have been studying Chile and we expect them to be very technical, with a lot of skill and players with good ball control. They play more to our kind of style. We are going in it to win but it will be a tough game, though we must be positive. We started badly against Austria and now we must play like the African champions we saw in the second half. I want them to come out of the gates faster this time." Eddie Hudanski, Congo coach.
