The Colombian frontman, who arrived at Naturena at the end of December from Mamelodi Sundowns, is already well aware of the task at hand as he looks to influence the fortunes of Steve Komphela's outfit.
“We need to fight if we want to reach the semi-final. We need to be ready from the moment that the referee blows the whistle to kick-off the game,” Castro told his club's website.
“We want to score early. Baroka always approach their games with a ‘do-or-die’ attitude, they have nothing to lose and everything to gain.
"They can’t be underestimated. This means that we must be focussed from the start and take care of business with a sound game plan and a determination to win.
“We need to look forward as well. The Nedbank Cup is an opportunity to win a trophy this season.”
The much-anticipated clash is scheduled to kick-off at 20h15.
