China 0-1 Costa Rica
60 mins: Li Tie becomes the first China player to be booked after a trip.
58 mins: Paulo Wanchope is put through but a combination of a high bounce and the attention of Wu Chengying mean the ball goes off for a goal-kick.
56 mins: Costa Rica make their first substitution as Hernan Medford comes on for Rolando Fonseca.
55 mins: Wu Chengying gets down the left wing and sends the ball across the Costa Rica goal but Yang Chen coming in at the far post blasts the ball over.
49 mins: Carlos Castro' long-range speculative effort just dips over the bar as the second half already looks like being more entertaining than the first.

45 mins: In one of the best build-ups of the half, the ball finds its way to Wu Chengying but his shot is woeful.
Half-time: China 0-0 Costa Rica
39 mins: Paulo Wanchope is bundled off the ball by Fan Zhiyi and Xu Yunlong, giving Costa Rica a free-kick in a dangerous area. But an ineffective set-piece allows China to counter-attack but Yang Chen's shot at the other end is far too weak to trouble Erick Lonnis.
38 mins: Paulo Wanchope shows some neat skill on the right-hand side but his cut-back goes behind his team-mates.

12 mins: Rolando Fonseca collects a pass in the Costa Rica penalty area but a dangerous-looking high challenge from Li Weifeng succeeds in dispossessiong him.
10 mins: Ma Mingyu gets a lucky break of the ball and bursts into the Costa Rica half. He has plenty of options open to him but his cross sails harmlessly long.
5 mins: Costa Rica begin to settle down and start claiming more of the possession. Paulo Wanchope turns in the box and sends the ball across the face of the goal but none of his team-mates are in a position to take advantage.
3 mins: China, who have started the more brightly of the two teams, win the first corner of the match but a poor delivery sees the ball go out for a goal-kick.
