Kenyan international Vincent Oburu could mark his return to competitive action when Zesco United take on South African outfit Royal AM in the return leg of their CAF Confederation Cup second preliminary round.The former AFC Leopards and Wazito forward was left out of the squad that traveled to South Africa for the first-leg encounter but could be available for selection in the do-or-die affair.Oburu has been out of action since picking up a leg injury in March this year, returning to action in the friendly match against TP Mazembe last month, but he has been tipped as one of the players who could be game-changers for Zesco on Sunday when they need it the most.Oburu left out of Zesco United squad for CAFCC assignmentIn the absence of the Kenyan, Enock Sakala and Alfred Leku were tasked with leading the goal hunt down in South Africa but they were not effective enough to give Zesco the advantage going into the second half.##NAJAVA_MECA_6715903##”Oburu will be a likely major boost to the side’s ambitions of cruising past Royal AM when the two teams clash at the Levy Mwanawasa stadium on Saturday afternoon,” the club wrote on their portal.Speaking after the first-leg draw, Zesco’s tactician Mumamba Numba bemoaned the lethargic striking force in the first match despite the team creating so many chances.Zesco boss hails Oburu’s performance against MazembeHis sentiments point towards Oburu being included in the mix for the return leg, with the team needing nothing but a win to progress.“Our greatest concern is the striking force because we have created a lot of chances, but we are failing to get the goals. We controlled much of the first half of the game although dynamics changed in the second half. The soothing part is that we didn’t concede. Otherwise, it would have been better to get a win. We have a lot of work as we go back. We need to work hard and ensure that we win the return leg,” Mumamba said.
