1. Gavin Henson, London Welsh – Whatever you think of Mr Henson these days and his off-field antics, there’s no doubt there’s an extremely talented player somewhere under all the ego and fake tan. London Welsh didn’t exactly need the help of a signing to keep the club in the headlines this summer, but Henson has ensured all eyes will be on the Kassam Stadium anyway to see how the Welshman integrates into Premiership rugby. He didn’t exactly make a good fist of it with Saracens, but this really is last chance saloon. Watch this space.
