Rafael Benitez will leave Napoli at the end of the season even if he's offered a new contract.
Napoli president Aurelio De Laurentiis revealed earlier this week that Benitez can remain at the San Paolo "for the next five years" if he wants to.
However, sources said Benitez will quit Napoli when his contract expires in June, putting clubs in the Premier League on alert over his availability.
Benitez's future has been the subject of speculation for some time, but sources say the Spaniard plans to move on even if Napoli win the Europa League as he seeks a new challenge.
