On the prospect of Manchester United's Rio Ferdinand being made England's new skipper, McClaren explained the thinking behind his decision when in charge of the national team to appoint Terry.
"He has character and the players respect and listen to him in the dressing room.
"It just followed on from the great job he was doing at Chelsea to do the same with England. But other people have different opinions.
"An international captain is very important. He is your eyes and ears in the dressing room and can help you nip in the bud any problems before they could explode.
"It is important the captain is a leader and has great character in the dressing room. There are many who have been captain and cannot handle the responsibility.
"Terry will never lose what he has and his vocal side. But you need several leaders that drive the others on."
