"I'm not happy, but at the same time it's a challenge".
Combined with the Spanish manager making it clear he's been frustrated by the summer transfer window, and Newcastle's activity in it so far, Benitez speaking about Perez was always going to get attention, and that's nearly certainly why he did it.
"No, I made a decision to stay", said the 57-year-old.
Newcastle owner Mike Ashley promised to invest "every penny" gained from promotion in the first team after the Toon Army won the Championship last season but Benitez, who has repeatedly underlined the need to bolster his squad, admitted signing players has become increasingly hard because of the inflated transfer fees that have become routine in the Premier League.
"He went to the Championship knowing that his job was the get the club back into the Premier League, then thinking he could go one-step further and build and get bigger and better - that's what he wants and if he's not able to do that he won't be there for much longer".
Neymar leaves Barcelona for the final time
However, the tricks Barcelona turned to get Neymar would leave an indelible stain on the club's holier-than-thou image. But Neymar told reporters: "I've done nothing bad". " Before Neymar the value was $1 billion and today it is $1.5bn".
It has been no secret that Benitez has been frustrated with Newcastle's transfer activity, his search for a new striker looks set to continue. He says they're working hard to bring those players in and hopefully they can.
"We missed some targets at the beginning and I think we are paying for that ..."
Newcastle United legend Alan Shearer believes it's not guaranteed that manager Rafael Benitez will be at the club when Christmas arrives. "At the end of last season, Mike Ashley said he would give every penny he had to Rafa".
"I am not happy but at the same time for me it's a challenge". "For me, I'm not totally happy with what we did but I will try to do my best".
Asked about walking away, Benitez added: "No, I chose to stay". It has to be something you can not control.
