Dutch teenager Nathan Ake is battling to become a regular part of Chelsea's squad last season, and made the most of an opportunity in the club's final pre-season friendly.
Usually considered as a centre-back or defensive midfielder, the versatile prospect was picked against Real Sociedad at left-back.
While he will have to dislodge Filipe Luis and Cesar Azpilicueta to become a regular in the position, he demonstrated he is more than capable of playing at full-back.
Ake has been tipped for the top ever since featuring in the Europa League quarter-final for the Blues two seasons ago, and was part of the club's FA Youth Cup winning side last season.
Championship side Derby County had been linked with taking him on loan earlier this month, but Jose Mourinho appears determined to keep him around.
His versatility ensures he can cover in several positions, and he was particularly impressive against Sociedad in the 2-0 victory.
Here is a look at how Chelsea fans reacted to his performance via Twitter:

I quite like Ake as a fullback, looks extremely comfortable & seems to enjoy himself. Slight tweaks and he's just about perfect. #CFC— Tarun (@SW6Opinion) August 12, 2014
