JOHANNESBURG, July 17, 2018 (News Wires) - Former title-holders Mamelodi Sundowns suffered a shock 1-0 away defeat to Port of Togo on Tuesday at the CAF Champions League groups. Physically formidable Kissimbo Hundele scored the only goal on 39 minutes in Lome, netting from close range as the visitors appealed for offside. It was another setback in west Africa for the 2016 African champions, who have never won a Champions League match in the region. In May, Sundowns conceded a late goal to draw 2-2 with Horoya of Guinea in Conakry after coming from behind to take the lead. After two losses, Port were considered the Group C pushovers, but they seemed more motivated than opponents who lacked want-away star attacker Percy Tau. Both sides squandered scoring chances and Port goalkeeper Jean-Rober Klomegan atoned for mishandling several crosses with a couple of brave blocks. TP Mazembe 1-0 Mouloudia Alger Five-time African champions TP Mazembe of the Democratic Republic of Congo maintained the only 100 per cent grouprecord with a dramatic 1-0 home win over Mouloudia Alger of Algeria. Only two minutes of regular time remained in southern Congolese city Lubumbashi when Elia Meschak scored the lone goal in a top-of-the-table Group B clash. Mazembe have nine points and Mouloudia four from three matches and Difaa el Jadida of Morocco one and Entente Setif of Algeria none ahead of their later kick-off.
