Lazio midfielder Sergej Milinkovic-Savic has insisted that he is fully focused on staying at the Serie A club amid continued speculation over his future.

Premier League duo Manchester United and Chelsea, as well as Real Madrid, have been linked with a move for the 23-year-old, with Lazio president Claudio Lotito stating that he is willing to sell the midfielder.

However, Milinkovic-Savic, who recently returned to Rome following Serbia's World Cup campaign, told Football-Italia that he intends to honour his contract with his current employers.

"I'm happy to be back," the midfielder said. "I have a contract, you never know what happens in football, but my head is at Lazio and I'm focused on my team."

Milinkovic-Savic took his tally of international caps to seven after featuring in the World Cup in Russia.
