ABC medical drama Grey's Anatomy, which is one of the longest-running scripted television series of all time, has seen a lot of doctors and nurses come and go.

However, few characters made quite as much of an impact as Sandra Oh’s Cristina Yang, who appeared in the show from 2005 to 2014.

It comes as no surprise, therefore, that Grey's Anatomy fans will be ecstatic to know that Oh is no longer ruling out a return for the character.

While not fully confirming a return to the iconic Shonda Rhimes series, Oh did tease that she “doesn’t know” whether she might come back after telling fans “a hard no” for many years.

Oh said in an interview with Entertainment Weekly: “For the longest time, it has always been a hard no. And it's just...I don't know. I just don't know.

“When you finish something, it's a deep process...I just cannot tell you...I can't stress to you enough how consciously I tried to fully process leaving."

She added: "I don't feel the need to revisit, but I also profoundly understand the audience's love for this character, because I've seen it for the past 10 years. That's the part that makes me just go, hmmm."

During the podcast, Capshaw claimed she heard that Oh "maybe might come back."
