AB De Villiers Optimistic About South Africa's Test Future

South African skipper AB de Villiers is optimistic about the Test's team future despite the current run of poor performances. While injuries and poor form to key players have hampered the team's progress this summer, De Villiers says there is enough depth to take the team forward but some patience and time to allow players to settle into their roles will be important going forward. The fourth Test against England starts on Friday. (Video courtesy: Cricket South Africa)
