The 25-year-old was put under the spotlight for his display in the 6-1 defeat by Tottenham
Manchester United's humiliating defeat at home by Spurs back in October appeared to signal the beginnings of drastic change at Old Trafford. That, added to the viral clip of the Red Devils keeper berating his left-back, made for grim reading for the English defender.
But it was Shaw who emerged to face the scrutiny of the television cameras after the 6-1 hammering at the hands Jose Mourinho's side.
'It really hurts. It's embarrassing and we've let a lot of people down,' he said. 'We've let ourselves down and the staff down. We were too quiet and naive. There were many mistakes and we need to do more.

Shaw faced the media after that defeat and has since gone from strength to strength
'It was a lack of concentration and then a mistake, another mistake, another mistake. We switched off. I was embarrassed on the pitch. We need to take a long hard look at ourselves. We are nowhere near it at the moment.'Insurance Loans Mortgage Attorney Credit Lawyer
The transformation in results following that Spurs defeat are well documented: 11 wins, four draws and one defeat - 31 goals scored, 14 conceded. The Red Devils can reclaim top spot in the table with victory over basement boys Sheffiield United tonight.
The change has been attributed to Bruno Fernandes, whose monstrous efforts since joining last January have provided a shot in the arm for everyone involved at the club.
But in Shaw, United have a bona fide leader who is hitting his stride at just the right time for Ole Gunnar Solskjaer's side.

Shaw's upturn in form represents a remarkable turnaround for the 25-year-old.
The summer acquisition of Alex Telles from Porto would have come as a stark warning to the full-back, with the Brazilian earmarked as an almost certain starter.
However, Solskjaer has kept the faith in his English full-back, and his man-of-the-match performance at Anfield earlier this month provides a perfect indicator of Shaw's progression this season.
