Suddenly, the 20-year-old England youth international is in the best shape of his life.
Prior to his introduction in the 68th minute, his Dortmund team was trailing Club Brugge in their Champions League debut on Wednesday.
Dortmund’s first two goals were from Gittens; his first was a fortunate deflection, while his second was an incredible effort that required numerous step-overs before cutting to his right.
Gittens was chosen player of the match, and Dortmund won 3-0 thanks to his impressive effort.
Had Serhou Guirassy not been chosen to take a late penalty ahead of him, he might have even scored a hat-trick.
Former Liverpool defender Stephen Warnock told Champions League Match of the Day, “As a defender, it is your worst nightmare, electric, the speed he has, the movement of the hips.”
“You can’t get anywhere near him, such is the speed of feet.”
Dortmund supporters are used to the winger’s immediate and significant influence when he comes off the bench; in August, the team defeated Frankfurt 2-0 thanks to two goals he scored in the closing minutes.
However, his Champions League performance has garnered attention from supporters worldwide.
