Mertens overtakes Maradona's Napoli goal record, pledges to stay

The Belgian striker headed in the equaliser after 85 minutes in Naples to surpass former Argentinian ace Maradona, who hit 81 league goals between 1984 and 1991.

Mertens is now the third best Serie A scorer in the club's history, behind Antonio Vojak, who hit a record 102 league goals between 1929 and 1935 and Slovakian Marek Hamsik, who achieved 100 before leaving to play in China this season.

"I'm very happy to have overtaken Maradona and to be a part of Napoli's history," said Mertens, 31, who arrived in southern Italy in 2013 from PSV Eindhoven.

"We must be proud of the our second place."

"The future? If I want to score goals in Italian I have to stay. I have always said that I feel good here, I want to continue doing important things with this shirt."

Mertens said he was enjoying playing under Carlo Ancelotti who took over from Maurizio Sarri this season.

"With Ancelotti my role has changed. The place behind the striker is mine. I have more freedom and it shows."

Mertens has scored 14 goals this season including the last three games.

Both of Napoli's Serie A titles were won under Maradona in 1987 and 1990.

The club are 16 points behind champions Juventus but ten ahead of third-placed Inter Milan with three games to play.
