Napoli are currently leading the way in Serie A, having lost just one of their 20 league matches, and the club are hopeful of maintaining their high standard until the end of the campaign.
The Partenopei are now said to be on the verge of announcing new contracts for two first-team players in the shape of Allan and Chiriches, who both joined the team back in 2015.
Former Brazil Under-20 international Allan has been in impressive form this term, scoring three goals from 20 league appearances, and he is set to extend his stay until 2022.
Chiriches has been used sparingly this season, featuring just five times, but he has looked solid when asked to play and he is also close to penning a deal that will see him tied to the club until 2022.
It is said the new deals will be announced in the next couple of days.
