The left-back was part of Gareth Southgate's side that suffered shoot-out heartbreak against Italy in the final, but it has become apparent that Shaw was playing through the pain for his country, after suffering a blow to his ribs against Germany in the last 16.
According to the Telegraph, Manchester United will now wait to assess the left-back, whose sole goal at the European Championship represented the fastest to be scored in a final since 1964, ahead of the 2021-2022 campaign.
The former Southampton academy product was in scintillating form throughout Euro 2020 as he recorded three assists in six games to add to his final strike past Gianluigi Donnarumma.
His three assists, two against Ukraine and one against Germany, could only be bettered by Switzerland's Steven Zuber (four).
The 26-year-old (10) created two more chances than any other player for England and, amongst the defenders at the tournament, only Spain's Jordi Alba (12) provided more opportunities.
Shaw was as testing down the left flank for United throughout the domestic season, too, as he created 72 chances. Bruno Fernandes (95) was the sole United player with more to his name.
The Red Devils must now wait for news of Shaw's fitness - potential another post-Euros blow for Ole Gunnar Solskjaer after Marcus Rashford underwent shoulder surgery.
