Mauricio Pochettino refused to be drawn on Toby Alderweireld's transfer situation amid interest from Manchester United and Roma.
A £25 million ($31m) release clause in the Belgium international's contract is widely reported to have expired with less than two weeks to go until the end of the transfer window.
The defender insisted his attention is fully focused on Tottenham when asked about his future earlier this week.
Alderweireld was named captain when Spurs beat Juventus 3-2 in the International Champions Cup and the 30-year-old made an appearance from the bench in the 2-1 defeat to Manchester United on Thursday.
