Tottenham Hotspur extended their unbeaten run in the Premier League to five games on Wednesday night but were held to just a point against West Ham United at the London Stadium.

And if anything, it merely showed chairman Daniel Levy that this current squad is far from the finished article and that manager Antonio Conte may well need another piece or two before tonight's 11pm transfer deadline.

Heung-min Son endured another disappointing, if not disastrous, showing on the left wing. And the Italian head coach kept him on for the game's duration in a desperate attempt to see him refind his scoring boots, despite the prospect of another five games in a two-week window.

SofaScore graded the South Korean as the Lilywhites' worst-performing player on the night and it's easy to see why, given he registered fewer touches (35) than even goalkeeper Hugo Lloris (45), which goes to show his severe lack of influence on the pitch throughout the 90 minutes.

The French shot-stopper saw more of the ball, whilst Son also saw two shots blocked, failed to deliver an accurate cross from four attempts and didn't register a key pass or successful dribble as he endured a nightmarish attacking display in east London.

Elsewhere, he lost possession 13 times, meaning he was involved in a turnover of possession every 2.7 touches and he appeared lightweight in his battles, losing 72% of his duels, both aerially and on the ground, as per SofaScore.

There are perhaps two key things to take from Son's downtrend in form - firstly, he cannot do it all, so he certainly needs reinforcements and Richarlison may not be enough when those around him also need a rest too. And secondly. there's a gaping creative void, whether that be out wide or through the middle.

The 30-year-old dynamo, who cost Spurs around £22m in 2015, cannot do it all - as he and Harry Kane often have done over the last few seasons.

Arguably, the north Londoners have never truly replaced Christian Eriksen and it's now Conte who is suffering from the consequences, which may well be why the club have been linked to many creative stars, ranging from AS Roma's Nicolo Zaniolo to Leicester City's James Maddison.

Those are certainly candidates to fill a no.10-like gap, whilst players such as Adama Traore of Wolverhampton Wanderers and Dan James of Leeds United are wide options.

Either way, it's now on Levy and sporting director Fabio Paratici to get at least one more deal over the line, ideally, a creative sort that can lower the burden on Son and his attacking counterparts.
