Mesut Özil's father is planning legal action after a document surfaced that appeared to show the authorisation for the transfer of his son, Germany international Mesut Özil, to Manchester United, according to the Köln Express.

The German newspaper possesses a letter which seemingly signs off on a deal to send Özil to Manchester United from Real Madrid. The Germany international was linked with United during the summer window, but eventually completed a deadline day £42.5m switch to Arsenal.

The letter - dated August 7, 2013 - includes the signature of Mustapha Özil but he claims it's a forgery. And he's planning to hire a lawyer to investigate who's behind it.

Speaking to the German publication - as translated by - Özil snr said: "I would have never thought something like this was possible. Someone has pretended to be me.

"They've used my name to link it to Manchester United. They have even signed my name! That's not a trivial crime. We're now looking into the matter."

Of course, Özil moved to Arsenal, not United, and the former-Real Madrid star has quickly settled into life in the Premier League.

He had a hand in all three goals during Arsenal's 3-1 win over Stoke City at the Emirates Stadium on Sunday to add to his debut assist against Sunderland.

Manchester United, in contrast, moved for Marouane Fellaini in a deadline day move of their own. The Belgian international made his first United Premier League start in the 4-1 defeat to rivals Manchester City at the Etihad Stadium on Sunday.
