The defender is currently away with England at Euro 2024, preparing for the round of 16, after Gareth Southgate's men clinched top spot in Group C by drawing 0-0 with Slovenia.
Although injury has prevented Luke playing for club or country since United's game at Luton Town in February, the left-back is hoping to be involved now the tournament has reached the knockout stages in Germany.
While representing the Three Lions will be his current focus, Luke is likely to think back to arriving at Old Trafford 10 years ago, when a deal was struck with Southampton and he became Louis van Gaal's second signing as United boss, the day after Ander Herrera's transfer.
