Since Brexit, and with the UK no longer part of the European Union, clubs now have to navigate a more complex work permit system to ensure players – especially those who are yet to establish themselves at the top level – are able to move to England.
Austria youth international Ndukwe doesn’t currently have enough points to obtain a Governing Body Endorsement (GBE) to obtain a work visa.
There is another route into the squad, through taking up an Elite Significant Contribution (ESC) slot, which is awarded to foreign players who do not qualify for the standard GBE.
Premier League and Championship clubs have up to four ESC places available, based on the percentage of minutes clubs gave to their England Qualified Players (EQP) in the previous campaign.
But clubs are not entitled to all four spots automatically.
The magic number is 35% of minutes, which means clubs can use four ESC players. Dropping below that begins to reduce the number of ESC slots available.
Liverpool’s percentage last season means they only get one ESC place, which has already been taken by Senegalese 18-year-old Mor Talla Ndiaye.
Last season, Freddie Woodman, Gomez, Rhys Williams, Curtis Jones, Trey Nyoni and Rio Ngumoha were the only English players in Liverpool’s squad, playing a collective 83 times in the Premier League.
This comes after Liverpool lost the likes of Trent Alexander-Arnold, Jarell Quansah, Tyler Morton and loaned out Harvey Elliott.
