After a 1-0 win over Ulsan HD which put them top of Group F, Mamelodi Sundowns will secure their last 16 spot at the FIFA Club World Cup if they pull off a shock win over German giants Borussia Dortmund on Saturday.

Mamelodi Sundowns got off to a winning start at the Club World Cup in a match delayed by a weather warning and played before empty stands.

Iqraam Rayners scored from point-blank range in the 36th minute to give Mamelodi Sundowns a 1-0 win over Ulsan HD after an hour-long weather delay in the group stage of the Club World Cup.
