Another rebuild is on the cards for the Australian's second campaign in charge, but the futures of a plethora of fringe players are overshadowed in a thick cloud of uncertainty.
Here, Sports Mole takes a look at the Tottenham players whose contracts either expire at the end of June, or in the summer of 2025.
Which Tottenham players are out of contract this summer?
Ryan Sessegnon
Age: 24
Position: Left midfielder
Transfer value: £8.6m
Joined: August 8, 2019
Joining fee: £23.1m
Tottenham appearances: 57
Tottenham goals: 3
Honours
None
Regarded as a top prospect following his 2019 capture from Fulham, Sessegnon's Tottenham move has not worked out as intended due to a wave of injuries, and the 24-year-old will be allowed to leave for nothing this summer.
Which Tottenham players are out of contract next summer?
Son Heung-min
Age: 31
Position: Left winger
Transfer value: £38.5m
Joined: August 28, 2015
Joining fee: £25.7m
Tottenham appearances: 408
Tottenham goals: 162
Honours
Asian Games (1): 2019
Promoted to club captain for the 2023-24 season and excelling with the armband, Son Heung-min should be rewarded with a new contract in due course, but as things stand, the South Korean will be available on a free in 2025.
Fraser Forster
Age: 36
Position: Goalkeeper
Transfer value: £1m
Joined: July 1, 2022
Joining fee: Free
Tottenham appearances: 21
Tottenham goals: 0
Honours
Scottish Premiership (4): 2011-12, 2012-13, 2013-14, 2019-20
Scottish Cup (3): 2010-11, 2012-13, 2019-20
Scottish League Cup (1): 2019-20
Retaining his status as Tottenham's number two last season, 36-year-old Fraser Forster may not have much time left in a Tottenham shirt, especially after Brandon Austin's recent contract extension.
Pierre-Emile Hojbjerg
Age: 28
Position: Midfielder
Transfer value: £15.4m
Joined: August 11, 2020
Joining fee: £14.2m
Tottenham appearances: 184
Tottenham goals: 10
Honours
Club World Cup (1): 2013-14
Bundesliga (4): 2012-13, 2013-14, 2014-15, 2015-16
DFB-Pokal (3): 2012-13, 2013-14, 2015-16
Formerly a mainstay of the Tottenham midfield, Pierre-Emile Hojbjerg slipped down the pecking order when Postecoglou arrived and is expected to be sold this summer before a free transfer in 2025.
Ben Davies
Age: 31
Position: Left-back
Transfer value: £8.6m
Joined: July 23, 2014
Joining fee: £10.8m
Tottenham appearances: 330
Tottenham goals: 9
Honours
EFL Cup (1): 2012-13
The longest-serving player at the Tottenham Hotspur Stadium, experienced left-back Ben Davies also struggled for regular minutes in 2023-24, but his situation remains on the unclear side.
Sergio Reguilon
Age: 27
Position: Left-back
Transfer value: £10.3m
Joined: September 19, 2020
Joining fee: £25.7m
Tottenham appearances: 67
Tottenham goals: 2
Honours
Club World Cup (1): 2018-19
Europa League (1): 2019-20
Following a pair of Premier League loan spells with Manchester United and Brentford, Sergio Reguilon is back in North London but seemingly has no future with Tottenham, who should be open to acceptable bids for the Spaniard.
Alfie Whiteman
Age: 25
Position: Goalkeeper
Transfer value: £427,000
Joined: 2008
Joining fee: Free
Tottenham appearances: 1
Tottenham goals: 0
Honours
None
English goalkeeper Alfie Whiteman helps to fulfil Tottenham's home-grown quota, but the 25-year-old has only ever made one appearance for the Lilywhites and will seemingly have to move on if he wishes to enjoy regular game time elsewhere.
Joe Rodon
Age: 26
Position: Centre-back
Transfer value: £6.8m
Joined: October 16, 2020
Joining fee: £10.3m
Tottenham appearances: 24
Tottenham goals: 0
Honours
None
Joe Rodon shone for Leeds United on loan during their unsuccessful bid for Premier League promotion, and having failed to live up to expectations at Spurs, a permanent move to a Championship club may be his best bet.
Japhet Tanganga
Age: 25
Position: Centre-back
Transfer value: £1.5m
Joined: 2009
Joining fee: Free
Tottenham appearances: 50
Tottenham goals: 0
Honours
None
Once regarded as one of Tottenham's stars of the future, Japhet Tanganga has not hit the heights expected of him in North London and is now expected to join Millwall on a permanent deal following a strong loan spell.
Giovani Lo Celso
Age: 28
Position: Midfielder
Transfer value: £13.7m
Joined: August 8, 2019
Joining fee: £27.4m
Tottenham appearances: 108
Tottenham goals: 10
Honours
Copa America (1): 2021
Ligue 1 (2): 2017-18, 2018-19
Coupe de France (2): 2016-17, 2017-18
Coupe de la Ligue (2): 2016-17, 2017-18
Trophee des Champions (2): 2017-18, 2018-19
CONMEBOL-UEFA Cup of Champions (1): 2022
After surprisingly staying on at Tottenham for the 2023-24 season, Giovani Lo Celso was only able to make a fleeting impression under Postecoglou and is surely heading for the exit door.
