Jamaal Lascelles
Lascelles often leads by example as captain of Newcastle, and is an imposing figure in attack and defence.
The 24-year-old has three vital headed goals from set-pieces this campaign; all of which were key in providing wins for his side.
Since joining the Magpies in 2014, Lascelles has gradually proven himself to be a defender of high quality and certainly of Premier League standard.
His battle with Saints striker Guido Carrillo will be an important one as the Argentine looks to bring his teammates into play, with Lascelles deflecting away any threat from attacks.
