The Verdict
This reflective message from O'Nien highlights the strong relationship he has built with the Sunderland fanbase.
He has been a fantastic servant for Sunderland since joining from Wycombe in 2018 – amassing 174 appearances and giving 100% in every game no matter which position he is asked to play – and the supporters have recognised that.
The utility man has established himself as a player that Alex Neil can trust and you'd imagine he'll be a regular fixture once again next term.
The 27-year-old's performances over the past four years have justified a move up to the Championship and he's now got one with Sunderland.
It's clear to see just how excited he is for it.
