Thomas Muller admits he's considering his options at Bayern Munich.

The striker has been linked with a January move away, with Liverpool and Manchester United linked.

And Muller told Kicker: "A coach has to make difficult decisions before each game.

"However, there has been a trend in the past five games that does not make me happy. If the coaching team only sees me in the role of a substitute player in the future, I have to think about it.

"I'm just too ambitious for that."
