4. Waisake Naholo (Highlanders to London Irish)
The All Black powerhouse winger finally arrived in London in July, having stayed in New Zealand throughout the Covid-19 pandemic. The 26-cap back, who last featured for the All Blacks in 2018 and was part of the 2015 Rugby World Cup-winning squad, has looked good when he’s on the pitch but has been limited to just four appearances. Not fantastic value for money, but still has time to prove his worth.
