Manchester City goalkeeper Joe Hart is wary of the Euros' new ball.

The official Euro 2012 football is the adidas Tango12 and England No 1 Hart admits they are once again incredibly fast.

He said: "They are really quick with movement but we've come across them before.

"The first type of Jabulanis took everyone by surprise but footballs change and you have to adjust as a keeper.

"It's the same for everyone. France will play some pretty football around the box so we have to be ready for that."
