CHANGZHOU: Qatar U 23 Captain Ahmed Moein Ali on Sunday said the Qatar team is brimming with confidence having accumulated six points from two matches at the AFC U-23 Asian Cup.     Group A leaders Qatar, who just need one point to secure a quarter-finals berth, have beaten Uzbekistan and Oman in their two matches at the Changzhou Sports Centre.     Rivals China lost to Uzbekistan on Friday after easily beating Oman 3-0 in their opening match of the tournament.     "We have a very important game against China coming up and we are preparing ourselves well. The team is ready for the match," Moein said on Sunday.     "We are doing very well in this tournament so far and we already have six points," he added.     Moein said Qatar expects to see a huge Chinese crowd turning up for the clash today.     "At the AFC U-19 Championship in Myanmar in 2014, we played against Myanmar and there were nearly 30,000 spectators there," Moein said of Qatar's title winning triumph three years ago.     "I think the team will face the same sort of challenge against China as the stadium will be full. Nevertheless, we are ready," he added.
