Solid Qatar progress to quarter final tie against South Korea

South Korea vs Qatar: Bento calls for clinical quarter-final performance

Qatar vs Iraq live online: preview

The final game of the round of 16 sees Group D runners-up Iraq play Group E winners Qatar. Qatar's three wins in three, against Lebanon, North Korea and Saudi Arabia, saw Felix Sanchez's side score 10 goals without conceding. Their opponents in those games managed just three shots on target, fewer than any other side.

Iraq took six points from their games against Vietnam and Yemen before being held 0-0 by Iran, who claimed top spot to set up a clash with China. Having seen Jordan, another side boasting a perfect defensive record after three games, get knocked out by Vietnam on penalties, however, Iraq head coach Katanec says nothing is certain.

"Our form is good but we must be on our toes against Qatar," he said at a media conference. "Jordan went into their match against Vietnam having not conceded one goal but the first one they did was enough to eliminate them from the tournament."

"Qatar will be huge challenge as they are very adept in changing tactics and formations. My message to the players is that we must be quick to adjust to Qatar. We have been taking it one match at a time and I have not pressured the players by saying we must win. The players, however, are determined to give their countrymen joy and we will give our best against Qatar."

Former Barcelona youth coach Sanchez, who has worked his way through the Qatari ranks to his current position as senior team boss, acknowledges the importance of remaining focused for this next big challenge to avoid the same fate as Jordan.

"This is the knockout stage and it all boils down to one match. One defeat and we go home," he said at a media conference. "We too didn't concede a goal in the group stage but all that can change in an instance and we could be eliminated. This is something that we don't want to happen and the players know that there must be full concentration."
