Kolkata:East Bengal defeated city rivals Mohammedan Sporting 2-1 to maintain their winning ways in the ONGC National Football League in Kolkata on Thursday. After being 0-1 down in the first half, Mohammedan Sporting, yet to get over the five-goal shock from Dempo in Goa, showed enough grit to get the equaliser in the 52nd minute. But their joy was shortlived as East Bengal notched up the lead again after six minutes. Apart from some flashes of brilliance by the Sporting players, the game was in the control of East Bengal medios. East Bengal forward Asim Biswas headed home a floating cross from teammate Debabrata Roy in the 33rd minute to begin their quest for the second straight win after beating HAL 3-1 at Bangalore. Sporting players, charged up after the lemon break, pressed on for the equaliser and received the reward in the 52nd minute with Habibur Rahman heading in a cross by Bijen Singh. But after getting the equaliser, they seemed to lose their way as East Bengal mounted pressure. The red and white brigade's winning strike came in the 58th minute when Bonisse Ambani scored an excellent goal from a volley after receiving a low cross from Malsawma just outside the Sporting box.
