Nigeria will take on the Croats on Saturday on the back of unimpressive showings in the build up to the competition.
However, the Franco-German has during the team’s media conference on Wednesday, assured that they are ready for the first game.
“Now the team is ready. We are physically ready. We have two training sessions today (Wednesday) and we will see the players again,” Rohr stated.
“We have a full week in Russia and the players showed good commitment. Technically and tactically we have three days to work on some things.”
He added that “We have our team in our heart already but we will wait till the final moment before we give it out.
“We spent nine days in Austria, two training sessions everyday.
“This preparation gives us a possibility to see who is fit physically and who needs more time to be ready.”
Speaking further, he said “Croatia watched us against England and Czech Republic. The game will be a good one for both teams. It is an important game for the two teams as it is good to start with a win.
“They are more experienced than us but we have young team. There is big enthusiasm in the team. You know this desire, big enthusiasm can make a team perform better.”
