Couples has been captain himself three times before, most recently in 2013, while Johnson has taken part in the Presidents Cup four times as a player but never as either a captain or assistant.

Stricker has been a captain's assistant once before and captained the US team to victory last time out in 2017.

The event, pitting the US against the rest of the world minus Europe, will take place at the Royal Melbourne Golf Club from December 9 to 15, with 14-time Major winner Woods able to name one more assistant prior to the competition.

Couples - the 1992 Masters Champion who has played alongside Woods at the Presidents Cup twice - said supporting Woods this year will be "a very special experience".

"Plus, to return to one of my favourite venues, Royal Melbourne, is going to be a real treat," he said.

"The fans in Australia really know their golf and create an unbelievable atmosphere for the players, so I'm excited to return and help this team win."

Johnson - a two-time Major champion - has played alongside Woods in the Presidents Cup three times, while Stricker, who has 12 wins on the Professional Golfers Association Tour but has not won a Major, captained the US team to victory at the last Presidents Cup in 2017.

Woods said Johnson will "bring a lot of passion and energy" to the team.

"He's so well respected among his peers and we've grown close on Tour throughout our careers," Woods said.

"I value his advice and he can help me make important decisions during the week."

Stricker said he was "humbled" to be picked by Woods.

"I look forward to helping him in any way he may need with his captaincy, just like he helped me in 2017."

The Presidents Cup, which takes place every two years, does not boast any prize money and players are not paid for their participation.

Instead each competitor allocates an equal portion of the funds generated to a charity of their choice.

Since its inception in 1994 the competition has raised more than $49.1 million (£38 million/€43.4 million).
