Napoli pays tribute to Diego Maradona, takes outright Serie A lead
As well as Mertens — who has taken over several of Maradona's records at Napoli — Piotr Zieliński and Fabián Ruiz also netted to help Napoli move three points clear of second-place AC Milan, which earlier lost 3-1 at home to Sassuolo.

Dries Mertens scored twice as Napoli beat Lazio 4-0 to take the outright lead of Serie A on the night it paid tribute to soccer great Diego Maradona.
As well as Mertens — who has taken over several of Maradona's records at Napoli — Piotr Zieliński and Fabián Ruiz also netted to help Napoli move three points clear of second-place AC Milan, which earlier lost 3-1 at home to Sassuolo.
It was a special night for Napoli fans as the match came three days after the one-year anniversary of Maradona's death. Maradona led Napoli to its only Serie A titles in 1987 and 1990 and is considered a god-like figure in the southern city.
A statue to the former Argentina player and coach was unveiled in the Stadio Diego Armando Maradona, while the players wore special shirts.
And Napoli got off to a quick start as goals from Zieliński and Mertens put it 2-0 up with less than 10 minutes on the clock.
The second of Mertens' goals, in the 29th minute, was a brilliant effort from the edge of the area that curled into the top left corner. It was a club record-extending 139th goal for Napoli from the Belgium forward.
The 34-year-old Mertens was given a standing ovation when he was substituted in the 64th.
Another delightful goal from Ruiz that arrowed into the top corner from outside the area capped a memorable night for Napoli.
Lazio, which is led by former Napoli coach Maurizio Sarri, slipped seven points below fourth place.
