Nick Mordin isn't too impressed with Nathaniel:

As to Workforce:
"For me, WORKFORCE (38) is the horse to take out of the King George. He looked sure to cruise past Nathaniel but then dived across the track. He ended up about twenty yards or over six lengths further across the track from his rival than when he began his challenge. Seeing that he only lost by two and three quarter lengths it's hard to argue against the idea that he would have been a clear cut winner had he kept straight.
I really liked the way that Workforce sustained his effort despite drifting so badly. But I'm not keen on buying the idea that he hung simply because he got cut into on the home turn. The fact is Workforce has now hung three of the four times he's run in fields of seven or less. What's more he has lost every time he's run in a field that small but won all four times he’s run in fields of eight or more.
I'm now inclined to think that Workforce needs a bit of cover in a race otherwise he tends to pull hard and hang. When he gets it he is quite some horse. As long as the ground doesn't come up too fast for him at Longchamp I have to give him a serious chance of pulling off the Arc double. However I wouldn't bet him ante-post right now. His most likely warm up for the Arc is the Prix Foy, a race that hasn't drawn a field bigger than six in nearly two decades. If my read of Workforce is right then he'll lose that race and likely drift to a very attractive price in the Arc betting soon after."
