Temperature could play an important role in this lunchtime match.
"I feel they need to worry about us more than we need to worry about them".
"We have a certain stability and I liked how hard my team worked (against Belgium)".
A team of hard-working, organised, honest and homely footballers who don't play for the biggest teams in the world and seem un-fussed and unruffled by the modern pressure to be glamorous and selfie-driven.
"It should have been worse", he said. This is the second game of the group stage for both teams and it means that a result is needed for both teams.
His team were ahead at half-time (in fact they could have two up but for Manuel Neuer) and even when Marco Reus ended goalkeeper Robin Olsen's record of five clean sheets in a row they never buckled - and remained unsafe on the break. Nigeria is the other. It was not a whipping as expected though and it has to be remembered that this team did pip the US to qualification.

Carlos Sanchez received a red card in the third minute against Japan, forcing his team to play almost the entire match a man down.
"They don't have a lot of individual stars like Belgium and [Eden] Hazard, but they work well as a team, especially on ball recovery". The ominous message referenced Andres Escobar, who was shot and killed days after returning to Colombia from the 1994 World Cup, where he scored an own-goal in a loss to the host United States.
While England may be one of the most formidable national teams in world football, Panama has every right to feel it can go toe-to-toe with the 1966 World Cup champions.
"It will be like a final", he said.
"My concern is that my players work well, that they stay true to their style and keep up their good work".
