Williams delighted to captain Wales
Dragons boss Chris Coleman opted to switch the armband from Arsenal midfielder Ramsey to Swansea skipper Williams ahead of the current international break, in which Wales play a double-header of World Cup qualifiers against Scotland at home on Friday and Croatia away on Tuesday.
Asked if had believed the armband would come his way again, Williams said: "Probably not to be honest, because I thought Aaron was doing a good job. I was just concentrating on trying to play my best for Wales. So probably not, but I'm happy."
He added: "He (Coleman) asked me if I wanted to do it - he didn't tell me I had to. He called me and said he had spoken to Aaron. Obviously I was over the moon, and he just said we would have a chat when we got to camp."
Asked about Ramsey's reaction, Williams said: "I have spoken to Aaron and he said congratulations. We kind of laughed and that was it really - no big deal. We get on fine."
Wales head into the Scotland clash bottom of Group A having lost their first two fixtures, a 2-0 home reverse to Belgium and then a humiliating 6-1 defeat in Serbia.
Those results last month extended the Dragons' losing streak since Coleman was appointed as manager to five games, including the 1-0 defeat to Costa Rica in the Gary Speed memorial match.
Williams feels the contest at Cardiff City Stadium is "definitely a must-win match" and has stressed that the players want a victory for their manager, on whom the pressure has been increasing.
Referring to Coleman, Williams said: "After the results I think you are always going to get criticised like that, especially him - being the manager, it is obviously going to fall on his shoulders.
"But I think all the boys really like him and we have enjoyed working with him. We really want to win for him as well - I think that is true in this case."
