"I walked straight into the changing room and was told the score," Furman said with a broad smile after learning that third-tier Oldham had scored a shock 3-2 win over Premier League opposition.
The midfielder, who featured in a 2-2 draw for South Africa against Group A rivals Morocco that clinched a place in the last eight for the host nation, said he got straight on the phone to Oldham's two-goal hero Matt Smith.
"We share a house together," Furman said. "I can only imagine the party back there tonight.
"I'm totally thrilled with both results. What a day for me."
Furman is now hoping to play against Everton in the fifth round on Feb. 16 or 17, one week after the Nations Cup ends.
