Tottenham have added Juventus' Gleison Bremer, 26, to their list of centre-back targets as they look to strengthen their defence.
The Brazilian has interest from other Premier League sides also, but Spurs are one of the clubs at the front of the queue.
The club are ready to make some moves in the transfer market in a bid to give new manager Ange Postecoglou the best chance of getting off to a positive start in his new role.
Spurs conceded 63 goals in the league last season, the sixth most, and it's likely Postecoglou will see the defence as something to work on as soon as he can.
