Tottenham are set to decide whether to push through a move for Wolfsburg's Micky van de Ven or Bayer Leverkusen's Edmond Tapsoba at this stage as they try to revamp their defence.
Spurs are looking to overhaul Ange Postecoglou's backline after the team conceded 63 Premier League goals last season. The club have already moved to bring in a new goalkeeper between the sticks in highly-rated £17million Italian Guglielmo Vicario from Empoli, followed by the £40million capture of midfielder James Maddison.
With winger Manor Solomon expected to follow on a free transfer later this week, the aim is to bring in a new centre-back for Postecoglou to work with before the club flies out on July 14 to Perth for the first leg of their summer tour to Australia, Thailand and Singapore.
