Zlatan Ibrahimovic has told Manchester United he is not at the club to “waste time” and that they must think big and show they are prepared to match his ambition if he is to remain at Old Trafford next season.

The Swede is in talks about taking up an option to extend his contract for another 12 months, although the 35-year-old has an offer to move to the Major League Soccer with LA Galaxy and has also been linked with Napoli in Italy.

And in the most candid admission yet about his future, Ibrahimovic has thrown down the gauntlet to United by insisting he is unwilling to tread water for the final few seasons of his glittering playing career.

United want to sign Atletico Madrid and France striker, Antoine Griezmann, this summer and Ibrahimovic left the club under no illusions that he expects them to make a statement in the transfer market.

“I’m 35,” Ibrahimovic said. "A lot of things have to be settled. It’s not like I’m 20 and I have another five or 10 years. Probably I have one, two, three years so everything depends on what you want and what the club wants, what the vision of the club is because I said from day one I didn’t come here to waste time, I came here to win. If you want to win bigger then you have to create bigger.
