Willian was part of the Brazil team which beat El Salvador 5-0 in a friendly, while Matt Miazga started for USA in their 1-0 win over Mexico.
It was a comfortable victory for Brazil who were 3-0 up at half-time thanks to a fourth-minute Neymar penalty and goals from Richarlison and Philippe Coutinho. Everton’s Richarlison added his second five minutes into the second half to make it 4-0, with Marquinhos completing the scoring right at the death.
Willian replaced Douglas Costa early in the second half and played on the right-hand side of the front three.
The Chelsea attacker was quickly involved in the action and almost scored shortly after coming on, with his low drive well saved at the end of a quick Brazil break.
Elsewhere, Miazga played the full game as USA recorded an impressive victory against Mexico.
The defender, currently on loan at French side Nantes, partnered Cameron Carter-Vickers at the heart of the back four and performed well as the home side kept a clean sheet against strong opposition.
The only goal of the game arrived 19 minutes from time with Tyler Adams firing home the winner for the hosts.
Miazga was joined in the USA side by Paris Saint-Germain’s Timothy Weah, son of former Chelsea striker George Weah, who came out of retirement to play in an international friendly for Liberia yesterday at the age of 51. Weah featured for 79 minutes as Liberia were beaten 2-1 by Nigeria.
