It's been a persistent rumour, but it's hard to see the logic of it.
Quins have invested a lot in getting him back to fitness, and if he stays fit the Dombrandt/Clifford/Chis combo could be our starting back row for some time to come - I can't see Robshaw carrying on for much longer past the RWC.
The Chiefs could probably do with additional cover, but he'd be fighting for a starting position with local lads and fan favourites, and when fringe internationals move it generally sets their case back a year or two. Unless there's a lot of cash involved (and bear in mind he can't be a marquee player) or he's just desperate for silverware, I can't see the appeal for him moving.
Now that he's back to both form and fitness I really hope Quins do everything they can to hold on to him
