Gernot Rohr, Super Eagles’ coach, says Nigeria must have total concentration against Argentina on Tuesday when they meet in a crucial 2018 FIFA World Cup Group D match.

NAN reports that Rohr at a pre-match press conference on Monday said “Nigeria will play total football with intense attack against Argentina” in the match at St. Petersburg.

“We are going to play a wonderful mass attack. We are going to play good game on Tuesday. We are going to defend the colours of Nigeria.

“We will focus on our game, as we are not concerned about Lionel Messi’s skills, even though he is a good player.

“In football, there is no mercy. So, we will not show any mercy for the Argentina team,” he said.

He also allayed fears about poor officiating, saying “we are not afraid of any referee. All we need to do is play good football to get results.”

Rohr promised to work on the team to take advantage of set-pieces and score from free-kicks, a failure which has been the bane of most African teams at the competition.
