PRETORIA - Former France manager Henri Michel had to be driven away by riot police to escape angry fans after his Mamelodi Sundowns team were knocked out of the South African Cup on Sunday. A Reuters witness saw Michel being escorted by heavily armed riot policemen and then being bundled into their vehicle before being driven away from Pretoria's Super Stadium with irate supporters chasing after him. Sundowns fans chanted "Michel must go" after the Cup holders suffered a 1-0 home defeat after extra time by unfancied Platinum Stars. Sunday's loss followed a 4-1 defeat by champions SuperSport United in the Pretoria derby on Thursday, a result which effectively ended Sundowns' championship hopes. Michel, who has coached extensively across Africa, took over at Sundowns in October and has had varied results with his expensively assembled squad. Club owner Patrice Motsepe, a billionaire mining magnate, was also accosted by angry fans demanding the sacking of the French coach. Motsepe promised an announcement on Monday.
