Chelsea have a gem on their hands and they know it. Levi Colwill is one of the most exciting young defenders in world football, and he's left-footed.
It's a valuable commodity in the modern game with passing range, athleticism and line-breaking ability all of heightened importance. In a three-man defence there is a slot perfect for Colwill, especially considering the left centre-back role has been long occupied by right-footed players in recent years at Stamford Bridge.
Before Benoit Badiashile was signed in January it had been a position for Antonio Rudiger and his no-nonsense style before Kalidou Koulibaly arrived with the promise of being a game-changing addition. His move ultimately failed, though Badiashile has become an immediate fan favourite for his early performances.
