Perth-born and raised Williams has played for the Young Socceroos and Olyroos, but not for the senior side.

The younger brother of Socceroo Rhys Williams was recently named in Australia's standby list for the friendly with Kuwait.

The 24-year-old said Arnold is keeping an eye on him.

"I made the stand-by squad after getting a message off the coach which said keep doing what you are doing which was nice,” he told the Rotherham club website.

"I kept myself ready in case the call came, and hopefully now I can keep starting games, keep my form to a high standard and try to impress again."

Williams joined Rotherham last year and helped the club get promoted from League One via the playoffs.

This season the winger has been a regular for the Millers, playing in every one of the Yorkshire side's 12 league fixtures.

Currently Rotherham sit in 19th spot in the Championship with three wins, two draws and seven defeats.

Williams said the competition for places at the club keeps everyone performing at their best.

"At the start of the season the gaffer always said that he wanted to strengthen in the middle to help out Will (Vaulks) and Matt (Palmer)," he said.

"Now we have Ryan Manning and Richie, and we also know young Ben Wiles is making great strides too. There is real competition now, which is great and it gives us that chance to play with three in midfield knowing Semi can do a great job in there as well.

"The gaffer is all about good competition for places and you can see that now right across the midfield."
