That's certainly the assumption from cynical supporters after the north London club made a huge gaffe on their website, when they assigned Danny Welbeck with the same shirt number as the Chilean.
The 27-year old has one-year remaining on his current deal and Sanchez continues to give Gunners fans anxiety by stalling on his contract negotiations.
Arsenal quickly fixed the problem and changed Welbeck's number back to his usual 23. However it hasn't stopped fans from assuming the worst.

On the Arsenal website. Well, I guess that's one way to break the news...

Seems like on the arsenal website, if you order a shirt you can get "Welbeck 7" on the back. They know something we don't...
