Graham Potter has revealed why he used Raheem Sterling as an advanced wing-back in Chelsea's 1-1 draw with Salzburg in the Champions League.

The Blues were held to a frustrating stalemate in Potter's first match since succeeding Thomas Tuchel in the Stamford Bridge dugout.

Chelsea started with a back three formation, with Sterling playing wide as a winger and wing-back, akin to how Potter used Leandro Trossard at Brighton. The former Man City star ended up breaking the deadlock.

Speaking to BT Sport post-match, Potter explained why he decided to play the 27-year-old in a role largely unfamiliar to him.
