The coach has admitted that he was forced to schedule in an extra training session in order to improve his team's performance and fitness ahead of the World Cup
Brazil coach Luiz Felipe Scolari says his team have to improve their defending ahead of the World Cup.
The 65-year-old was left fuming after a training session on Sunday, which had been planned as a day off for his squad.
He was unwilling to divulge details after the session, but did so a day later – pointing out “poor defending” and the openness in his team's play as areas to improve.
Scolari said it was the worst he had seen Brazil since their 2-1 loss to England at Wembley in February last year.
"We have planned for this first week for a long time and have achieved everything we set out to achieve in the first week. We strictly followed our schedule in all departments," he told reporters.
"I wasn't expecting a training day on Sunday but we managed to fit in a session - but it wasn't our best work.
"It was poor defending and there were far too many spaces all over the pitch. We haven't played that badly since England defeated us last year.
"We have to keep improving because we must not forget we are only one week away from the start of the World Cup."
As much as he would like another week to work with the team, Scolari is eagerly awaiting Brazil's tournament opener against Croatia on June 12.
"As a coach, I also want another training week to prepare the players, but I think honestly speaking, deep inside I want the 12 June to come around as quickly as possible," he said.
"I want to play the opening match against Croatia today, it feels like it is time already.
"We can't stop thinking about what is wrong and what is right with our team. We have to give it our all and do the best we can, that's what I am thinking now."
