English Premiership In April 2011 Manoa signed for
English Premiership side
Northampton Saints for the 2011–12 season. Northampton were impressed with his ball skills, pace and physicality. In autumn 2011 Manoa hit the ground running for the Saints with a series of powerful performances in the early rounds of Premiership Rugby and worked himself into Northampton's starting rotation. A series of outstanding performances earned him man of the match awards in wins over Castres and Harlequins, and the big second row fast became an integral part of the Saints squad. Over the course of the 2011-12 season, Manoa played in 18 Premiership games for the Saints, with 14 starts. Manoa was named by ESPN to the 2011-12 Premiership "Dream Team." On February 15, 2012 Manoa signed a three-year contract extension with
Northampton Saints. He was honoured with the Northampton Saints Supporters' Player of the Year for the 2012-13 Premiership season. During the 2013-14 season Manoa replicated his success and subsequently was short-listed for the RPA Player's Player of the Year award and the Premiership Player of the Year. Furthermore, for the second year in succession Manoa was voted the Saints Supporters' Player of the Season. In 2014 Manoa started as Northampton beat Saracens to win the
Premiership. He achieved his first English Premiership hat trick on October 11, 2014 as Northampton dominated
Sale Sharks 43-10. Just two months later he achieved another hat trick in a substitute appearance in which Saints drubbed
