Newcastle United boss Eddie Howe hailed two-goal Bruno Guimaraes after victory over Brighton.
Guimaraes was signed from Lyon for £38million in January, competing with Kieran Trippier for the title of the first marquee signing of the new Toon era.
Asked if the Brazil international was a bargain even at that price, Newcastle manager Howe said: "I find it difficult with that number, but I would say that he's a bargain in today's current climate.
"He's absolutely a bargain because he's had a huge effect on the team and the club. In today's market, that is a relatively modest sum - which I can't really believe I'm saying - but it is.
"It's an amazing thing for us to have him, it's not just the player, it's the person as well. I can't say how good a person he is.
"He's a pleasure to coach and be around. He's a really positive person, an energiser and someone I love to coach and be with. I think everyone here connected with the club - me, the players, the supporters - absolutely love him."
