Few signings in recent years have made more of an impact than scrum-half Kahn Fotuali'i did after joining the Saints from the Ospreys last season.
Supremely consistent, Kahn also regularly showed the ability to sprinkle games with his stardust – most notably in a man of the match performance against Quins in the Challenge Cup semi-final.
Perhaps most importantly of all, the Samoan has pushed fellow scrum-half Lee Dickson on to new levels and the ability to rotate between two outstanding 9s has only been to the Saints’ and their own benefit.
Kahn had been tipped for full All Blacks honours after making his mark in Super Rugby for the Crusaders alongside Dan Carter. Instead, Fotuali’i chose to represent Samoa and after a man of the match performance on his 2010 debut he went on to play in the 2011 Rugby World Cup.
In his two seasons in Swansea, Kahn tuned out for the Ospreys 39 times, including in the Pro12 final success over Leinster and a Heineken Cup man of the match display against Leicester.
In the 2013/14 season he played 34 out of 39 games for the Saints, coming off the bench in Cardiff for the Amlin Challenge Cup final before starting eight days alter at Twickenham.
