Porto striker Jackson Martinez has conceded that his men will be in for a tough encounter when they play Napoli in the Europa League.
After beating Eintracht Frankfurt, the Portuguese side set up a Last 16 tie with the Partenopei in the competition in two weeks.
And the striker has admitted that his team will have to be at their best if they are to make the quarter-finals.
“Napoli are a great team,” he told reporters. “We’ve already played them in a friendly last summer, and we saw how good they were there.
“They have players who can make the difference in any match, whether that’s in Serie A or in the Europa League.”
