At just 18 years old, Mainoo has emerged as one of United's standout performers this season, despite facing adversity early on due to a foot injury sustained during pre-season. Undeterred by this setback, Mainoo's resilience and exceptional talent have shone through, earning him a prominent role in his team's last 16 matches across various competitions.
His recent performance against Liverpool showcased his exceptional abilities, maturity and skill beyond his years. This display, coupled with his consistent excellence since breaking into United's starting lineup under manager Erik ten Hag, undoubtedly influenced Southgate's decision to fast-track Mainoo's ascent to the senior squad after initially selecting him for the U-21 setup.
