Dries Mertens says Napoli are feeling confident ahead of their last-16 second leg against Barcelona in the Champions League.
The two teams will meet again at the Camp Nou on August 8 with the scores tied at 1-1 after the first leg in Italy.
Antoine Griezmann’s away goal means Barca have the slight edge, and Mertens knows his team will have to go on the attack.
“It’s not going to be easy but we’re feeling confident. The key is that we have to score because if we don’t score, we will be out.
