Brazil have been drawn in Group E along with Switzerland, Costa Rica and Serbia. The five-time World Cup winners will play their first game of the tournament against Switzerland on Sunday.

"I am not taking any medications, although I have already undergone eight surgeries. I cope with my emotions, I have a lot of experience in that. Of course, there are certain expectations from the World Cup. I am focusing on the main goal, not wasting my energy. We did a lot of work ahead of the World Cup. Tomorrow we will face some difficulties in the match against Switzerland," Tite told journalists.

He added that the Brazilian fans always supported the national team.

"But they [fans] expect only one thing from us - to bring the trophy to Brazil. You can't make your fans happy when you play for a draw... I set the bar high, we'll have to play under a lot of pressure," the head coach added.
