The Netherlands midfielder recently stated that he will consider his options in the next two weeks, but the Nerazzurri boss wants him to make a decision as soon as possible
The Istanbul giants announced at the weekend that they have agreed terms with the Nerazzurri over a winter move, but added that they are still in talks with the creative midfielder himself.
Sneijder stated on Saturday evening that he is in no rush to make a final decision on his future, but Moratti is now running out of patience and has told the Dutchman to make up his mind.
"We want an answer by the end of the day. It would be professional from him if he made a decision shortly," the Inter boss told reporters.
Nevertheless, despite Moratti's latest comments, Sneijder is unlikely to make a decision on his future any time soon.
The 28-year-old is reportedly having doubts about a move to the Turkish league, and would prefer a transfer to one of Europe's top league competitions.
