“When I went to the Copa America, I thought Rafael would sign for Newcastle. But he didn’t and when Rafael said he was going, my possibility to stay at Newcastle went down straight away.
“Rafael brought me to Newcastle and he fought with the owners to bring me there.
“So when Rafael said goodbye, I felt I would have to say goodbye as well. I understood in that moment I would not sign for Newcastle.”
Rondon has since joined Benitez at Dalian Yifang, signing a lucrative three-year deal with the Chinese Super League outfit.
Benitez had wanted to sign Rondon permanently last summer but the Magpies refused to pay his £16.5million release clause because he had little-to-no sell-on value.
The Magpies hierarchy are happy to spend big on new signings, as long as they have the potential to be sold for profit further down the line.
“Maybe a few years ago, Newcastle would have given me a contract," he added.
“But it looks like the owner’s rule is that, ‘Because he’s 29, when I sell I don’t get more money from what I’ve invested in him’.
“I get that because, for the owner, it is a business.
“But I showed to all of them that even though I am 29, I am still scoring goals, I still assist my team-mates, I am still working really hard, I still feel like a young guy.
