Atletico Madrid could be facing a headache over Kieran Trippier's future due to the Brexit laws being introduced in 2021.
Trippier joined the Spanish side from Tottenham in 2019 on a three-year deal reported to be just over £20million.
However, despite having two more years left on his contract, Atletico are on course for a Brexit headache over the defender, according to Mundo Deportivo.
The UK is set to formally complete their exit from the European Union at the start of 2021, which will see Trippier become a non-EU player.
