Wayne Rooney has confirmed his interest in captaining both Manchester United and England.
The forward is considered by many to be the favourite for the role at United when they lose current skipper Nemanja Vidic this summer.
England meanwhile could also be in need of a new captain before long, with speculation that Steven Gerrard may not continue after this summer's World Cup.
"I've done it a few times and, if the manager wants me to be the captain, I would have no problem with that," Rooney told club magazine Inside United.
"I would take it with both hands. However, it is down to the manager, because it's his decision on whoever he feels is the right person to lead the team. I'm sure he'll make that decision when the time comes.
"I think, whether you've got the armband or not, I always feel I'm quite vocal on the pitch. I try to help the players when I feel I can and say what I think. I believe that's the most important thing, to be honest and say what you feel. If you say what you believe are the right things, you need to keep doing that."
On England he added: "You don't know what Steven is going to do in the summer, only he knows.
"It'd be a great honour to captain my country but, again, it's the manager's call and I'm sure he'll have a few contenders."
Rooney also revealed that he has already been taking his responsibilities as a senior player seriously by helping out some of the younger players like Adnan Januzaj.
"I've stayed out after training with Adnan a few times," he said.
"Even just working on free-kicks and crossing. It actually benefits me as well and it benefits him.
"I am trying to help him get better and better, which I feel he is doing, and I think young players need to practise all the time, especially coming into the side. Senior players also need to keep practising to stay on top of their game so it works for both of us."
