Kurt Zouma says it is "really not a problem" for him to play at left-back as Chelsea await reinforcements in defence.
Following Filipe Luis' return to Atletico Madrid, Jose Mourinho has been left short of experienced cover at the back and he said earlier this month: "We cannot go to the Premier League with five defenders."
Chelsea have so far been unable to agree a deal for Everton centre-back John Stones and, while Augsburg left-back Baba Rahman is expected to complete a move to Stamford Bridge soon, the lack of options at present means Mourinho is having to look at creative solutions.
He has already played Zouma, a centre-back and occasional right-back, on the left side of defence when he came on Cesar Azpilicueta in the Community Shield, and the 20-year-old, who has also been used in midfield, said he is happy to take on whatever role is required of him.
"Because I'm right-footed I have never played at left-back," he told the club's official website. "It was different for me positionally so I had to learn quickly and adapt to it.
"It's really not a problem because the boss needed me in that position and I have to give everything for the team. We all have to think about the team first of all so I always do that.
"They were good experiences for me because I played the games and I always want to be on the pitch enjoying myself and helping the team.
"I'm feeling very well. I had some opportunities to play in preseason and play in some good games. Now the Premier League has started we are just focused on the next game. We are looking forward to it."
Chelsea have yet to hit top form since winning the Premier League title last season, having failed to win any of their preseason games in regular time as well as drawing their Premier League opener 2-2 at home to Swansea City.
Zouma, though, says this weekend's clash away to Manchester City is an opportunity to show their quality.
"We know we are playing against a good team on Sunday and it will be difficult, but we have a chance to win," he said. "I think it will be a very interesting game.
"It's a chance early in the season to show why we are champions. We want to defend our title. The season after a very good season is always hard but we have to show we are ready to try and do it."
