He has been linked with roles including that of FC Porto manager
Marco Silva has left his position as Hull City manager following their Premier League relegation.
The club were bottom of the table when he took over in January, but he had brought them out of the drop zone with four games to go.
They then won just one more point, and went down with a match to spare.
It is already understood Silva's already held talks with Portuguese top-flight club Porto about their managerial vacancy.
In a statement on the club's official website, Hull City said: "Marco was offered the opportunity to continue the work he has done in the four-and-a-half months he has been at the KCOM Stadium. Unfortunately, after considering his future, he has chosen to leave in order to further his career and departs along with Assistant Head Coach Joao Pedro Sousa, First Team Coach Goncalo Pedro and Goalkeeping Coach Hugo Oliveira.
"Although disappointed by Marco’s departure, we would once again like to place on record our appreciation of his efforts and those of his support staff. Despite only being in charge for a short period of time, the 39-year-old became a firm fans’ favourite and will be forever remembered for his efforts to maintain our Premier League status."
