Ilkay Gundogan, in his prime, shows Man City what Barcelona lacks.

Without the Germany midfielder, Pep Guardiola's team wouldn't be the same. 

He was a key component of Barca's victory over Atletico Madrid. 

You could name a number of Barcelona's standout performers from their 1-0 victory over Atletico Madrid.  

Most will highlight Joao Felix's virtuoso play against his parent club, where he scored the game's winner and gave his best performance in Catalan colors.  

Others might draw attention to Ronald Araujo, who prevailed in all six of his aerial duels while handling the highly effective Alvaro Morata. 

Additionally, there is a case to be made for Raphinha, Inaki Pena, or the floaty Frenkie de Jong. 

But perhaps the most impactful individual over the course of 90-plus minutes was the one who always seems to show up in big games.  

Indeed, that Ilkay Gundogan embraced the spotlight once again is of little surprise.
