Cape Town - Mamelodi Sundowns have had their preparations for Friday's CAF Champions League tie with Rwanda's Rayon Sports disrupted after their final training session had to be called off due to a floodlight failure.
The Brazilians are aiming to once again go far in the competition after winning the Champions League in 2016, before advancing to the quarter-finals in 2017 as well.
As such, coach Pitso Mosimane earlier said his team had done their homework on their opponents, saying: "We had people who went to watch their matches.
"I know that six of their players were in CHAN (African Nations Championship). We will check them individually, their strength and weaknesses."
However, a practice session in the nation's capital had to be called off on Thursday night after the floodlights at the facility they were training at mysteriously turned off just moments after it had begun.
Downs' official Twitter account said: "And just like that, our training session is cut short due to a ‘power failure'. Friday's first round first leg action gets underway from 18:00 at the Stade Amahoro in Kigali.
