Ghana coach Otto Addo has said that beating South Korea in their second group game would be challenging.
On Thursday, the Black Stars kicked up their 2022 World Cup campaign against Portugal at the 974 Stadium.
The four-time African champions were defeated 3-2 by the European side.
Ghana will look to win their second group game against South Korea on Monday at the Education City Stadium, which kicks off at 13:00GMT.
“And surely it will be very, very tough to beat South Korea because they are good. But now we have to win.
“We are under pressure but they are too,” he added.
The result moves Portugal to the top of the group, but with South Korea and Uruguay drawing 0-0 earlier in the day, the Black Stars’ setback today may not be too expensive.
Ghana will conclude their group stage campaign with a highly anticipated match against Uruguay at Al Janoub Stadium in Al Wakrah.
