Brighton boss Chris Hughton says Rafa Benitez is working wonders at Newcastle United.
The Spaniard guided the club to a 10th-place finish last season following promotion but received limited financial backing in the summer.
"With regards to what they've spent in the summer, the reason why they haven't spent perhaps what the other clubs have done, the only ones who are privy to that are the CEO, the chairman and of course Rafa," Hughton said.
"What I do know is that with the squad that he's got, what they've recruited and what they've spent - which is less than most clubs and far less than a lot of clubs - then I think Rafa has done a wonderful job with the players that he has.
"What you always have to do as a manager is work within the boundaries of what you have, and if that means being allowed to go out and spend big, big money on players then that's what it is and that's what you'll be judged on.
"If it's working with a group of players and spending less, then it's exactly the same, it's what you'll be judged on."
