Tottenham added a fourth new signing this summer when Joao Palhinha completed a season-long loan move from Bayern Munich on Sunday evening.
The former Fulham midfielder joined Mathys Tel - also from Bayern Munich - Kota Takai and Mohammed Kudus in arriving as new recruits in the summer transfer window.
Spurs have the option to buy the 30-year-old at the end of the season for around €30million (£26.2million) and his experience will surely only be of benefit to the young players in the midfield area - Pape Matar Sarr, Archie Gray and Lucas Bergvall.
But while four signings have been made, five players have also left the club. Mikey Moore became the latest, making the loan move to Rangers at the weekend. Alejo Veliz has returned to Argentina on loan to play for Rosario Central, while Sergio Reguilon, Alfie Whiteman and Fraser Forster all left at the end of their contracts.
Tottenham are not done there, though, and the final few weeks of the transfer window are likely to be busy for both incoming and outgoing transfers.
Spurs failed with a bid to sign Morgan Gibbs-White from Nottingham Forest in what will go down as one of the strangest transfer sagas of the summer.
And with James Maddison stretchered off with another knee injury against Newcastle in their final pre-season tour game on Sunday and Dejan Kulusevski having had surgery on his own knee injury, a new No.10 is imperative.
Given the significant move for Gibbs-White, Frank has already given the green light to sign a new No.10 and Spurs could reignite interest in Eberechi Eze, who has been heavily linked with a move to north London rivals Arsenal in recent weeks.
There are a number of senior players who should be on the way out of the club - namely Manor Solomon and Bryan Gil - but it is a number of youngsters that Frank has already made a decision on.
