Fred is reportedly set to undergo a medical at Manchester United on Monday ahead of completing a €50 million (£44m/$58m) move to Old Trafford.
But the midfielder was evasive when asked about his future in the wake of the Croatia victory.
"I'll still talk to my agents to find out the reality of it," said Fred. "I want to focus only on the team.
"It's a unique time, the World Cup. We have to try to forget things from outside."
Pressed further on his future, Fred added: "I'm going to talk to the people, meet my friends.
"I still do not know where I'm going."
While the 25-year-old is reluctant to speculate on when he could end up at Old Trafford, his national team coach is eager to see a deal done quickly.
Tite told reporters: "When there are negotiations involving a player, which is inevitable, the player will come to us and our guideline is solve it as quick as possible, so you can be fully focused with the national team."
