An impressive transformation.

While some Real Madrid players are enjoying a break ahead of the Club World Cup in the U.S., Arda Guler is putting in serious work.

Determined to impress new coach Xabi Alonso, the Turkish talent has been training hard — and sharing the grind online.

Fans have taken notice of Guler’s noticeably upgraded physique.

He’s certainly no longer the skinny teenager who arrived at the club last summer.
