Manchester City midfielder Fernandinho has had no problem playing at centre-half this season.
Fernandinho has stepped back on the request of manager Pep Guardiola.
"I think the biggest challenge of moving to centre-back for me was that, as midfielder, you are used to running a lot in front," he said.
"You go to the battle in the middle and you can lose the ball or you can win the ball.
"But at centre-back, you have a lot of space behind us, between the central defenders and the goalkeeper, and you have to pay attention to that because most of the teams who come to play against us look to play those kind of balls behind the back four. For me, at the beginning, it was a little bit strange adapting to that, but afterwards I was able to do it."
