Red Bull and Ricciardo are due to sit down over the course of the
first few races of the 2018 campaign to see if they can reach an
agreement over a new deal.
But while talks continue to be ongoing, Webber thinks the spotlight will be a little bit brighter on his compatriot.
"The stop watch is important - the first part of the year is very important for him. He knows that," Webber told The Age.
"He is on a tight rope. There is no question. Any driver comes to that
point in his career where it's negotiation time again on contract -
there is a little bit more in the air around the team
"I have been through that stability, in the middle of it where you
are just knuckling down, and, obviously, right on the edge where you are
waiting to renew your contract, whether it's you stalling or the team
stalling. I have been through both of those.
"At the end of the day, when the helmet is on, it can't affect you,
whether you have a five-year contract or a five-minute contract - you
have to deliver. The team sees that.
"They are measuring everything now, there is nowhere to hide which is
good for him because it sorts out the wheat from the chaff.
"That's why he has had a long career and continues to have long career because he deserves to be there."
Webber, though, does not think Ricciardo's future in F1 is under threat.
He added: "He is safe in F1. It's just a question if he is wants the
absolute perfect team in '19 and trying to get the No 1 status somewhere
in those teams. That's what he would love to achieve."
