Porto midfielder Nico Gonzalez says he knows everyone is writing them off against Arsenal.

Porto host Arsenal tonight for the first-leg of the Champions League round of 16.

Nico said: “I am convinced that we will pass.

"Anyone who isn't from FC Porto doesn't believe that, but I'm convinced that we're going to beat Arsenal at home and that we're going to London to settle the tie.

"What I can guarantee is that we will fight every minute of the two playoff games and give everything."
