Ki Sung-yueng returned injured from the Asian Cup.
The hamstring injury is said to be only slight and he could be ready to play in about a week.
But Ki has also decided to retire from International football at the age of 30 which he reached just over a week ago.
He was the South Korean captain for three years through the World Cup in Russia last year and talked about possibly retiring after that competition.
He played 110 times for his country with 10 goals.
He signed a two-year contract Newcastle last summer and before he left for the World Cup in late December he was in good form for Newcastle.
Ki Sung-yueng has retired from International football.
He will now want to concentrate on his club career and hope to get a contract extension may be in the summer if he continues to star for Newcastle.
This is what Ki has said:
“I’m going to lay down the huge honor and big responsibility of being part of the national team,”
“The 2019 Asian Football Confederation Asian Cup was my last appearance to represent Korea.”
“Throughout my career, it was more valuable than anything.”
“I want to express my deep gratitude to the fans, who have supported me over the years.”
“I hope for the best for the Korean football team – but now I’d like to focus on Newcastle United.”
Rafa will be pleased with this news as he became one of the manager’s most trusted players by the end of last year.
Ki is a class act.
