The Hungarian international started in midfield for his nation in a crucial 1-0 win in Armenia on Thursday evening, which kept them in a play-off spot in their World Cup qualifying group.
Meanwhile, West Brom ended a four-match winless run with a 2-1 triumph over Oxford United at the Hawthorns before the international break.
Ryan Mason started his Albion reign with 10 points from his first four games, but the Baggies have collected just three wins in the last 11 since.

Speaking to Hungarian media, Styles argued that performances have been to a good standard, but that results urgently need to follow suit.
"We need to start winning games. Despite the outstanding individual performances, we are currently in the middle of the table," Styles said.
"As for me, I feel in good shape. I help the team, but goals and assists are missing.
"I'm 25, one of my dreams is to play in the Premier League. For this, our good play has to be combined with results.
"The strongest league in the world is the English first division, the constant topic in the locker room is which team played what. I hope that one day we will reach this level too."

Styles went almost a year without featuring for Hungary after joining West Brom in 2024.
An injury kept him out of their 6-1 aggregate defeat to Turkey in the Nations League play-off in March, but he has started every game in their 2027 World Cup qualification campaign.
He has opened up about his early challenges at Albion and explained how hard he had to fight to earn a place in the team.
"After the Euros, I changed clubs and worked on my integration at West Brom," he added.
"At first, I didn't play enough to be selected. The manager's decision was understandable, it encouraged me to work hard and fight for my place in the team.
"Once I managed to fight my way into the starting line-up, it was only a matter of time before I would receive an invitation, but in March I couldn't be there for the Nations League play-offs due to a minor injury."
