Following a successful summer window which saw the Black Cats add great quality and depth to their squad as they embarked on their first season back in the Championship since their disastrous 2017/18 campaign, the Black Cats have strengthened once again this month.
Pierre Ekwah, Joe Gelhardt and Isaac Lihadji have all joined Tony Mowbray’s side this month as they embark on an unlikely push for the Championship play-off places - and there could be one or two more deals to be concluded before the deadline passes.
