Him and henry to arsenal would be amazing. Though not going to happen
Henry wouldn't be much more than a bench option at this point, and even then he'd probably be down the order. He's still got class, but he's becoming increasingly inconsistent and injury prone as he gets older. He had moments this MLS season where he was absolutely, 100% unstoppable...and others where he completely vanished. I don't think he's got the legs to handle the EPL anymore for anything other than short bursts.
Beckham's still got his ridiculous set pieces, if nothing else.
Either the worst great player or the best horrible player you'll ever meet.
