Chelsea defender Ben Chilwell admits he is still adjusting to playing left wing-back.
New manager Thomas Tuchel has preferred a 3-4-2-1 formation, with the club having gone 14 games unbeaten since the German took over.
Marcos Alonso was initially preferred over Chilwell, who was signed for big money from Leicester City last summer.
But the England international has started three of the last four league games and played well in the FA Cup quarter-final win over Sheffield United.
"My whole career I've been more used to playing left-back than left wing-back, but the formation we are playing suits a lot of players and it's working very well for us at the moment," the 24-year-old told the club's website.
"If I want to play, then I have to adapt my game to be able to play left wing-back as well as left-back.
"I'm working hard in training, and coming into games I'm asking a lot of questions where I can be positionally to improve so I can get more opportunities to play in that role.
"When you're playing wing-back you're already a lot higher up the pitch, whereas at left-back you're running on to things and using your speed to get up and down the pitch, which is my strength."
He added: "At left wing-back you're predominantly in the attacking third, which I've had to adapt to.
"Against Sheffield United I got a dubious goal and an assist so on the attacking side of things I showed I can play there as well as left-back.
"On the other side of things, when you've got two or three good players in each position that have different strengths it makes everyone train harder. That creates a good buzz around the place."
