Explained: Why Aaron Wan-Bissaka started at left-back over Diogo Dalot for Man Utd's FA Cup quarter-final victory over Liverpool

Ten Hag's decision stemmed from meticulous planning and a commitment to sticking with pre-established strategies. According to Daily Mail, Dalot had spent the entire week preparing to contend with Liverpool's left winger, Luis Diaz. When Jonny Evans withdrew due to a calf injury during the final training session on Saturday, Ten Hag opted to maintain consistency rather than alter his tactical approach abruptly.

To compensate for Evans' absence, Victor Lindelof seamlessly transitioned from left-back to central defence, while Wan-Bissaka assumed the left-back role despite a prolonged period of inactivity lasting over two months. Wan-Bissaka's inclusion was not solely due to necessity, his exceptional defensive prowess, particularly in man-marking Liverpool's danger man, Mohamed Salah, factored significantly into Ten Hag's decision-making.

The left-back position has posed challenges for United throughout the season, with Luke Shaw sidelined for extended periods due to thigh and hamstring injuries, and Tyrell Malacia still recovering from knee surgery. Meanwhile, Wan-Bissaka's versatility and readiness to adapt to unfamiliar roles epitomise the resilience and determination ingrained in him.

Bruno Fernandes and Scott McTominay also battled through physical challenges to secure victory and the duo was hardly able to walk after 120 minutes of high-octane action in the cup tie. The Red Devils will return to action on March 30 against Brentford in a Premier League clash after the international break.
