Shaw started the 1-1 draw with Tottenham at the weekend, but was replaced in stoppage-time by Ayden Heaven.

While there was no explanation from Michael Carrick regarding the substitution, footage quickly emerged on social media afterwards of the left-back limping as he made his Old Trafford exit.

With such a short turnaround in between fixtures, Man United fans had been fearing the worst about Shaw’s involvement in the Spanish capital.

The 31-year-old missed United’s league phase win over Sabah last month through injury and he may sit out matchday two as a result of his absence at Carrington on the eve of the Atletico fixture.

If Shaw is unavailable for selection it remains to be seen who replaces him at left-back as Patrick Dorgu and Noussair Mazraoui both remain on the sidelines after sustaining injuries during the international break.

Doubts: Luke Shaw and Kobbie MainooGettyMainoo, meanwhile, was also absent from the aforementioned session despite completing the full 90 minutes against Spurs and is now considered a major doubt for the Madrid game.

In more positive news for United, Matthijs de Ligt could make his long-awaited return to action after taking part in training along with Harry Maguire, Lisandro Martinez, Leny Yoro and Diogo Dalot.

Carrick will provide a full team news update at his news conference on Monday evening.
