What is Nani doing at Arsenal's training ground?

Does this picture show Manchester United winger Nani at Arsenal’s London training ground on the day of the Manchester derby?
Sportsmail exclusively revealed that Arsenal were planning a bold January swoop for the United and Portugal winger.

Caught red-handed? This picture was posted of Nani on Twitter claiming he was at Arsenal's training ground

The 26-year-old is out of favour at Old Trafford after a bust-up with Sir Alex Ferguson and an impasse over a contract extension, while Wenger looks to bolster his squad for the Champions League and Premier League run-in.
This picture was tweeted on Sunday by @TheFootballDad along with the caption: ‘Why is Nani at London Colney this morning when the Manchester derby is on…met him there this morning. Erm…I wonder.’

This way to Arsenal? How the Portuguese winger would look in a Gunners shirt

The young boy in the photograph appears to be wearing a Stevenage jacket, lending further credence to the claim that it is indeed Arsenal’s training ground at London Colney.
Nani believes his relationship with Ferguson is beyond repair and has privately conceded his future is elsewhere, but United have not totally shut the door on the player, whose contract expires in 2014.

Out of favour: Nani has fallen out with United boss Sir Alex Ferguson

The winger, who missed Sunday’s Manchester derby through injury, had a bust-up with promising United midfielder Davide Petrucci earlier this season. He has not played since he was hauled off during the Champions League match at Braga in early November.
