Germany and Bayern Munich forward Thomas Müller has revealed he turned down a lucrative offer from Manchester United in order to sign a new deal at the Allianz Arena this summer.

Müller emerged as one of Louis van Gaal's priority buys following the Dutchman's appointment at Old Trafford, as the player stalled on committing to a new contract with the Bundesliga champions.

The 24 year-old broke into the Bayern first team when Van Gaal was in charge of the club in 2009, and prompted speculation of a surprise reunion in Manchester after revealing he still maintains a special relationship with the Dutchman.

When asked of the option of joining Van Gaal at United this summer Müller said: "Of course. I was aware that I could earn more by making that transfer. The amount that foreign clubs were offering me was astronomical. But Bayern are my club, a change was not an issue for me," he told Bild, via Standard Sport.

United's transfer woes

Müller brought an end to speculation prior to the World Cup when he signed a new deal at Bayern that keeps him at the club until 2019.

United have been frustrated in their attempts to strengthen their squad this summer.

While the club confirmed deals for Luke Shaw and Ander Herrera in quick succession in June, further efforts have proved unsuccessful.

Bids for targets, reportedly handpicked by Van Gaal, Thomas Vermaelen and Mats Hummels have failed, while pursuits of Angel Di Maria and Arturo Vidal have so far proved fruitless.

The club are however on the verge of sealing a move for Argentine international Marcos Rojo.

Sporting Lisbon confirmed via their Twitter account on Tuesday a deal has been agreed with United for the 24 year-old defender, with the much maligned Luis Nani joining the Portuguese club on a season-long loan in return.

United later confirmed a deal had been agreed for Rojo with a move to be completed imminently, pending personal terms and a medical.
