Chalobah has just signed on-loan with Watford.
He told watfordfc.com: "When I was going through my growth spurt I played centre half and then moved back to midfield because technically I was good on the ball.
"It is something that I can do [play at the back and in midfield]. I'd like to improve myself as a player because at the end of the day it is still early in my career and you never know what the future holds.
"I couldn't say at the moment where I'll end up playing.
"I've still got time to develop and my body is still growing. Right now I just want to improve my reading of the game and I think this is the right place for it."
