Former Nigeria captain Jay-Jay Okocha is worried about the damage South Africa duo Percy Tau and Thembinkosi Lorch could cause to the Super Eagles defence in Wednesday's Africa Cup of Nations quarter-final fixture.
Nigeria and South Africa will rekindle their rivalry at the Cairo International Stadium with a semi-final ticket at stake in the continental showpiece.
The two countries met during the qualifying series for Afcon 2019, with Bafana Bafana winning the first leg 2-0 back in 2017, before Gernot Rohr's men claimed a 1-1 draw in Johannesburg last November.
After seeing Stuart Baxter's side upstage host nation Egypt in the Round of 16 on Saturday, Okocha has picked match-winner Lorch and Tau as the main threats to the Super Eagles' progress.
