Carlo Ancelotti's side, who have already qualified for next summer's World Cup finals, are facing Senegal in a friendly on Saturday.
The game at the Emirates Stadium kicks off at 16:00 GMT, a venue the Selecao have used eight times in the past.
Casemiro has linked up with the squad, despite being withdrawn during our 2-2 draw with Tottenham Hotspur, and Cunha is also looking to cement a place in Ancelotti's plans for next year's major tournament.
During a press conference, our close-season buy from Wolverhampton Wanderers illustrated just how much that would mean to him, after he missed out on a place in the 2022 squad in Qatar.
