​​Napoli president, Aurelio De Laurentiis has warned Dries Mertens and Jose Callejon over leaving the club amid rumours linking them with a move to the Chinese Super League (CSL), claiming that, "he is not prepared to make a major effort for them".


The duo who's contract with the club expires at the end of the season are yet to agree to new terms amid reports of interest from clubs in China. However, De Laurentiis has insisted that he will not offer them more than what they are worth and that moving to the Far East would be a big mistake.


"I'm absolutely not prepared to make a major effort for them. Each player has a value, depending on where they play, how they play, how old they are and what they do," he said to Sky Sport Italia, as quoted by ​Goal.



"If they want to sell themselves out in China, overpaid to live a life of sh*t for two or three years, it's their problem. I can't consider China to be competitive. China's far away. If they consider it to be close, it's their problem.


"In life, you have to choose whether to be happy and find a job you enjoy doing or work just for money. For me, money is a means and not an end; if it's an end for them then they should go to China." 


The 70-year-old film producer also stressed that he has no issues with club captain, Lorenzo Insigne, but that the player should become more peaceful. Napoli for their part are currently placed fourth in the Serie A table with 13 points from seven games, six behind Juventus and will need to pick up their form if they are to challenge for the league title this season.
