5. James O’Connor (Sale Sharks)
The big money signing failed to have the impact he wanted at the AJ Bell Stadium in his first season at the club, chiefly due to an ongoing ankle injury. However, with his latest surgery hopefully behind him the Wallabies international will be hoping he can transform the inconsistent Sharks into genuine top four contenders.
6. Francis Saili (Harlequins)
The talented All Black centre was also a new signing last season, joining Quins from Munster, but was limited to just five appearances due to injury. The centre has a lot more to give if he can get back to full fitness.
