Belgium head coach Roberto Martinez said on Sunday that his team expected to have a tough match against Japan in the World Cup round of 16 as their opponents have “incredible energy and could create problems for Belgium. We faced Japan not long ago in a friendly… I think in essence [the team] is exactly the same, footballers with an incredible, incredible energy… I expect a very tough game, a game that well have to be concentrated at all times because they [Japan] are capable of creating problems, Martinez said at the pre-match press conference. The head coach went on saying that the team was not underestimating their opponent and the match could go all the way to the penalty shootout.

Japan not preparing for penalties Speaking about the upcoming game, Japan head coach Akira Nishino stated that his side had something to show Belgium. We fought bravely in the group and I would like our team to be regarded as equal to Belgium. We did our best at the group stage but I feel and I know that the players still have something to show. We are in perfect shape ahead of tomorrows match, Nishino told journalists. As Akira Nishino announced, his side was not preparing specifically for a penalty shootout. Of course, I make the decision concerning the penalty shootout, and I need to know the situation in the team… I was appointed to this position [of the head coach] not so long ago. Our team has never prepared for the penalty shootout specifically. I dont think we should practice penalties during our training sessions. We havent done it, Nishino told journalists. He explained that the players mental approach meant a lot during penalties. We cant prepare for that [the penalty shootout], as mental approach means much… The main burden lies on the one who strikes, not on the goalkeeper, Nishino added.
