Diego Maradona congratulated Dries Mertens for overtaking him on Napoli's list of all-time leading scorers and urged his former club to do all they can to keep hold of the Belgium international forward.
Mertens scored twice in Wednesday's 3-2 Champions League win over Salzburg to move onto 116 goals for the Serie A club, one more than Argentine great Maradona.
The 32-year-old is now second only to Marek Hamsik (121) among Napoli's leading scorers, but is out of contract at the end of the season and has recently talked up a lucrative move to the Chinese Super League.
