Tottenham captain Son Heung-min will be assessed today after suffering a back injury in his side’s 2-1 defeat against West Ham on Thursday night.

Son took a blow to the back late on and hobbled off in the closing stages, with footage showing him writhing in agony on the bench as he received treatment from the club’s medics.

Spurs face a quick turnaround as they prepare to host Newcastle on Sunday, and manager Ange Postecoglou is uncertain over whether Son will be available to lead the team.

Spurs already have a lengthy injury list with James Maddison, Micky van de Ven and Rodrigo Bentancur all ruled out until 2024.

Richarlison and Pape Matar Sarr both came off the bench against West Ham, though, after recent injury setbacks.

Postecoglou revealed they came through the game well and should be fit to face the Magpies, as he declared there are no ‘significant’ fitness concerns other than Son.

‘Pape and Richy both reported OK after the game but we won’t be getting anyone else back I don’t think before the new year,’ he said.

‘There’s nothing, apart from Sonny, that looks too significant.’

Son accused Tottenham of being ‘soft’ after they failed to hold onto a lead for the fifth successive game against West Ham.

They dominated the first half and went in front through Cristian Romero, but failed to build on that as Jarrod Bowen and James Ward-Prowse turned the game in West Ham’s favour.

Postecoglou admitted his side have plenty of improvements to make from an attacking perspective if they are going to challenge at the top end of the table.

‘I still think our front third, we’ve got a lot of work to do. Unfortunately, that’s costing us at the moment in terms of results, but that’s the challenge for us. 

‘We’ve got to keep pushing on and trying to become better in those areas.’
