Reinforcing the full-backs remains a transfer priority in the summer
After a couple of seasons as an ever present, Kyle Walker seems to be struggling with an ongoing pelvic issue that has seen Kyle Naughton deputise for his fellow ex-Blade. On the other side of the defence, Danny Rose has made limited progress from his performances at Sunderland last year, where he looked a decent defender.
All three full-backs have had their issues this season, with Naughton's two mistakes almost proving costly on Saturday, and reinforcements/improvements on those positions should be a priority once the transfer window reopens. Luke Shaw's performance at left-back for Southampton was an impressive and enviable one.
Eriksen looks like he is coming into his own
The Dane gave the clearest sign yet that he is someone to build the team around, with an energetic performance for Spurs that proved to be the heartbeat of his side's attacking game.
With two goals and an assist, Eriksen impressed between midfield and attack and is bringing some much needed goalscoring threat to a Spurs side reliant on Emmanuel Adebayor. His brace on Sunday left him with four goals in four games, and eight for the season. Double figures would be a real achievement for the youngster in his first Premier League season.
There is hope left for Soldado yet
Sunday's match was a real chance for Roberto Soldado after the Spaniard had given a flat showing against Benfica a few days earlier, followed by an impressive cameo by Harry Kane.
With Adebayor injured Soldado was leading the line ahead of the youngster, and the ex-Valencia man produced an impressive performance which saw him pester the Southampton defence, provide several exquisite touches and passes, and set up Eriksen's second goal. As a £26 million striker he still needs to be adding goals to that all round play, but it showed that a little faith and a full 90 minutes may give Tottenham the player they had hoped for.
Kaboul deserves a new contract if he can maintain his fitness for the next couple of months
Tottenham's central defence has been unpredictable and unsettled this season, with all four players having suffered injuries and, unsurprisingly then, a lack of cohesion when pairing up.
A couple of years ago Younes Kaboul was Spurs' best defender, powerful, quick, and fantastic in the air, and the injuries that have plagued him recently have been a bitter blow to the player and club. With his contract set to expire in the summer, Kaboul has finally found enough fitness to make regular appearances, featuring as captain in the absence of Michael Dawson. Only recently turned 28, If he can carry on such fitness until the end of the season, and get a decent pre-season under his belt, he is well worth a new deal.
There is still plenty of work to be done on this Spurs side
Tim Sherwood would do well not to forget how poor Spurs were in the first half against Southampton, worryingly a feature of several Tottenham performances this year. Slow starts have often led to heavy defeats, and it looked like a similar occurrence on Sunday as Southampton ran the side ragged.
If Spurs, and their manager Sherwood, cannot remedy this feature of their game, they will continue to harbour aspirations they are unable to realise, not least when they visit Liverpool at the weekend. The Reds famously smashed Tottenham at White Hart Lane, leading to the dismissal of Andre Villas-Boas, and Levy and Sherwood, and hopefully the players, shouldn't just be settling for avoiding the same thing happening again, they should be wanting revenge.
