Well, I quite like both tuna and tomatoes. I need to lose some weight. Did he just eat tin after tin of tuna, or what?

I think it's just that for every meal he was allowed a carefully measured portion of tuna and tomatoes - probably ensuring he got enough protein without piling on additional carbs. He might have been able to mix in a few onions and some greenery to make a faux salad nicoise, I suppose. Bear in mind he would also have been training 3 sessions per day...

As for Dombrandt, while there's a long and honourable tradition of No 8s whose impact is as big as their girth, ranging from Walrdom and Easter to Deano himself, he looks to me like he could comfortably lose half a stone and trade another stone for muscle, and be a faster and stronger version of what he is today. The trick is to know what body composition makes the most of each player's talents.
