QPR boss Mark Hughes says new signing Andy Johnson hasn't arrived to replace someone.
Hughes told the Rs website: "I'm always looking for complimentary skills.
"If one player is adept at certain things, then another may be more adept at others, so it's important we strike a nice balance in all areas of the squad.
"Andy likes to get in behind defences and he's got good pace which is important.
"There are a lot of reasons why I've bought him in and they'll be there for everyone to see this season."
