It's only a training shirt, of course. Still, for Gooner and Red Devil alike, there's something not quite right about watching the former England captain wearing Arsenal's colors.
Fortunately for us, there's video evidence that it's all true. The clip in question appears above and serves as our Set Piece Video of the Day for this Wednesday. Enjoy, if you can.
If you hadn't heard, here's the story.
Beckham, the 37-year-old former Manchester United midfielder, is currently training with United's English Premier League rivals Arsenal in North London. Beckham parted ways with the Los Angeles Galaxy following last month's MLS Cup final (the Galaxy won their second straight league title with Beckham's help).
Since then, he's been popping up in various gossip pages and rumor mills. As January winds down, however, we still don't know where Beckham will play next. He hasn't ruled much out, so his next destination could be just about anywhere.
But, if Arsenal manager Arsene Wenger is to be believed, we know one thing for sure: Beckham's real destination is not North London.
"[Joining Arsenal] is not on the agenda," Wenger said (per ESPN FC). "He asked to come here to get fit. [It's] purely for fitness. There's no speculation about signing or anything. Maybe in June he has plans to play somewhere."
Now, after years of Wenger's coy routine, we all know better than to believe everything he says. But this time he sounds serious. To us, it doesn't sound like Beckham will play with Arsenal.
Could this all be an elaborate ruse? Or is it something else entirely?
