During the summer, Spurs head coach Ange Postecoglou made the decision to sign Guglielmo Vicario, making the Italian his number one ahead of Hugo Lloris.
While Vicario has made a positive impression at the Tottenham Hotspur Stadium, there is uncertainty over his competition between the sticks.
Fraser Forster and Brandon Austin, for varying reasons, are not regarded as long-term alternatives, while a recent report indicated that Lloris could be offered a mutual termination of his contract having not been under consideration since Postecoglou's arrival in the summer.
Although, on one hand, Spurs have a wide array of goalkeepers at their disposal, it is a position that may require strengthening, either in the short or long term.
According to Football Insider, Spurs have instructed scouts to monitor the development of Bazunu in recent months.
The 21-year-old is currently in his second season at Southampton since making a £12m transfer from Manchester City without making a senior appearance for the Premier League giants.
Despite the Saints' relegation from the top flight in 2022-23, Bazunu will be delighted with his regular game time, already making 54 appearances in all competitions.
Furthermore, Bazunu is also first choice for Republic of Ireland, earning a total of 21 caps and keeping his place ahead of Liverpool deputy Caoimhin Kelleher.
As it stands, Bazunu is fully committed to trying to help a Southampton side managed by Russell Martin earn promotion from the Championship, the South-coast outfit handily placed in fourth position in the standings.
Nevertheless, the report claims that Spurs have been left "hugely impressed" by how Bazunu has developed into a key player at St Mary's, initially having only earned first-team football with Portsmouth in League One.
Bazunu possesses a contract with Southampton until the end of 2026-27, while it is alleged that City have the option to re-sign their former academy graduate in the future.
From Spurs' perspective, a formal approach may not be made until the summer at the earliest, the North Londoners having other priorities at the midway point of the campaign.
