Manchester City great Yaya Toure says they must attack Real Madrid to be sure of progress in the Champions League.

Toure believes that may have to be the solution against Real Madrid because trying to hold onto the 2-1 advantage from the round 16 first leg could be problematic.

"I think it's going to be 50/50 because without fans it is complicated," Toure told Leyton Orient's channel, the League Two club where he has begun training to keep his fitness levels up as he gears up for a new challenge next season.

"Real Madrid will be in good confidence having won La Liga two weeks ago.

"You just have to win because to draw against Madrid...It is going to be hard for City if they don't score one goal."
