Lazio coach Maurizio Sarri is being linked with a return to England.
Sarri has guided Lazio through a superb season, with Champions League qualifying on the agenda.
Il Messaggero says Sarri has cast doubt on his future after asking for guarantees in the transfer market to remain with Lazio.
Sarri feels Lazio can challenge for the league title if they sign two midfielders, a winger and a striker.
The 64-year-old wants Lazio to assure him of these reinforcements before the end of the season.
Meanwhile, interest from other clubs for the former Chelsea manager, not least from the Premier League.
Tottenham, West Ham and Everton have Sarri on their wish list. AC Milan and Fiorentina are also interested.
