Manchester United must respond quickly to Real Madrid's mega offer for Lazio midfielder Sergej Milinkovic-Savic.

Sportitalia says Real Madrid are preparing a €150 million bid for the Lazio midfielder, who is also wanted by United and Juventus.

Madrid are reportedly prepared to offer Milinkovic-Savic a long-term contract worth €8 million per year.

United are also chasing the Serb, who has stated he grew up idolising Nemanja Matic.

At Juve, meanwhile, it's been claimed by their former director general Luciano Moggi that they already have an agreement for the midfielder.
