Porto midfielder Raul Meireles says they go to Arsenal with plans to win the second-leg of their Champions League tie.

The Portuguese champions lead 2-1 from the first leg.

Meireles said: "We will not be ultra-defensive in London. That's not our style and to try to play that way would be a disaster for us.

"Arsenal are a dangerous team in attack and to give them the ball would cause chaos for us.

"The big battle will be in midfield. We must stop Cesc Fabregas but also the other men in that area.

"I'm optimistic and our squad have the confidence and belief that we will reach the last eight."
