Liverpool and England midfielder Steven Gerrard feels his game has suffered because of his versatility.
The 28-year-old favours a central position but has frequently been used on the left and right with both club and country.
Gerrard said: "I've paid the price for being able to do a decent job in other positions. Other players don't get shunted around because they can't do it.
very best
"I can't go and play on the right or the left and become Kaka or Robinho, I just go out there, give 100% and do a steady job. I'll work hard, do my bit defensively and help the team. That's why managers do it to me, but it is affecting me.
"My game suffers when my position is changed. I'm a central midfielder and in the big games I want to play in the middle and show that I'm one of the very best in that position.
"I've played in my favourite position for England five times in 68 games. What can you do? I go into training with England and try to prove myself every day. Every England manager I've worked under knows where I want to play, but they pick the formations and I play where I'm told."
