The Australian knows that his team are under serious pressure near the midway stage of the season.
Spurs are mid-table in the lower half of the league and could soon find themselves adrift of the top six teams.
Speaking after a 1-0 loss to Nottingham Forest, Postecoglou said on transfers: “Not in years but I think in the context of where we're at at the moment I think it is an important one. I think if we add what we need to add and it fits the bill in what we're trying to do… “Our league position is not great but it’s super tight and we’re not that far off. Like I say, we're in the semi-final of the Carabao Cup and still in great position in Europe and there's the FA Cup.
“There's still everything to play for for us this year to make it a season where we can have success. But we need some help, the players need some help more importantly, and the club is working really hard to try make that happen.”
