Sir Frank Williams has admitted that Ross Brawn would be a 'great addition' to his team if he were to become available over the winter, although the 71-year-old has played down the chances of a deal being done with the current Mercedes team principal.

Brawn is now widely expected to leave his current role at the end of the season despite non-executive chairman Niki Lauda having said he was keen to keep the former Benetton and Ferrari man for 2014.

The 58-year-old is set to walk away having been unhappy with the way in which Mercedes has gone about rejigging its management structure in recent times, with Toto Wolff and Paddy Lowe set to take control.

Brawn has been linked with both Williams and McLaren for 2014 if he does depart and Sir Frank said he would be a strong addition to any team - although he played down the chance of any deal being struck with a man who worked at Williams in the early years of his career.

"Naively, perhaps, I am unaware that Ross is available," he told Sky F1. "When he was with us he was really extraordinarily clever in terms of engineering - he is very gifted - and I am sure he has accumulated infinitely more knowledge, just as much about what not to do as much as what he should be doing. So if he was to come he would be a great addition.

"I wasn't aware he was available. I may now have to contact him and I can say no more.

"The reason I am being hesitant is that I do employ people already and it is very unlikely that we could afford Ross, or that he would want to come to us etc, etc. All I would be doing if we didn't get Ross would be offending everyone at the team already."
