London 2012 Olympics, Hockey Test Event preview Where: Riverbank Arena, Olympic Park When: May 2-6 Who will be there? Men's: Great Britain, Australia, Germany, India Women's: Great Britain, Argentina, China, Korea What: Part of the "London Prepares Series', six of the world's best hockey nations travel to London for a five-day warm up event and the first to be held on the "smurf-turf." Besides offering all eight teams vital tournament time ahead of the Games this summer, the event will also be an opportunity to test the field of play, the video referral, timing, scoring and results systems. Can I get tickets? every session has sold out since tickets came on sale in mid-march. As such, the capacity for Sunday May 6 (classification and finals) has been increased and a few remain available. GB Women's captain Kate Walsh on opponents: Argentina; Luciana Aymar has been voted best in the world I don't know how many times, She's very skilful and very quick. You'd think she's playing with a 40 inch stick because she just gets to things no one else would. It can sometimes be their downfall because you can't just focus on one player. Rosario Lucetti does alot of leg work for them and is great in defence. Argentina are a very strong side and very dominant. China: in between Olympics they're a bit unknown so it'll be good to see them at the Test event. In the four year build up they have done a lot of testing so we always see different squads and set-ups. Maybe this time round we'll get a glimpse of their Olympics team and what they'll be like. They'll always perform very well and threaten without fail. Ma Yibo at the back has a great drag flick, Fu Baorong up front is lethal, Song Quingling is really strong and athletic and also has lethal shots. Korea: Park up front is one of the best forwards I have ever had to mark, she has it all. Lee and Kim combining at the back are dangerous, how they set up plays is awesome. GB Men's captain Barry Middleton on opponents: Australia: they're No in the world and the best team at the moment. They have a way of playing and an intensity about them, they're so direct, it makes it so hard for people to cope with them and teams do get overwhelmed. Their danger man is Jamie Dwyer, he is their go-to player. He scores goals, he can do anything really he's an all-rounder. World player of the year five times in seven years so that kind of speaks for itself. Germany: we always know what we get with them. They'll perform when it matters. They'll really turn up for the Olympics. They're European champions. They're youngish but not inexperienced. They will always be hard to beat and have a way of playing that all of them have followed since they were 10 years old. They're go-to guy is Moritz Fürste who plays midfield. He performs in every big game and has a bit of everything. He sets the tone of the way they play. India: we know what we get with them too, they'll be open and attacking. They're very skilful and have a lot of flair and they will crash balls into the D. Most of their games will be very exciting. Player to watch, I really don't know their squad that well but I would say Sandeep Singh is a massive corner threat.
