Speaking to Sky Sports, Palmer expressed admiration for the teenager's performances this season, particularly during Barca's thrilling but ultimately unsuccessful Champions League semi-final tie against Inter Milan, which ended in a dramatic 7–6 aggregate defeat.
"It's mad, innit," Palmer said. "I think he's the best player in the world, to be honest. Everything seems to go through him - and just when you watch him. Mad."
Yamal's composure and quality on the biggest stage have turned heads across Europe. The young forward notched five goals and five assists in the Champions League this season, playing a crucial role in Barcelona's deep run into the latter stages of the competition.
His influence wasn't limited to European nights. Over the weekend, Yamal scored a key equaliser in a 4–2 El Clasico win over Real Madrid - a result that virtually sealed the Catalan club's 28th LaLiga title.
"You can tell by the way he plays - he's confident and fearless," Palmer added. "I love watching him."
When asked what it's like to play with such confidence at just 17, Palmer laughed: "I don't know, I've never tried it."
Palmer himself has enjoyed a breakout season at Chelsea, emerging as a key figure under head coach Enzo Maresca. With the Blues currently fifth in the Premier League -ahead of Aston Villa on goal difference with two games remaining -the race for Champions League qualification remains finely poised.
Before then, Chelsea also have a shot at silverware, as they prepare to face Real Betis in the UEFA Europa Conference League final on May 28.
While Palmer focuses on his club's strong finish to the season, his glowing praise of Yamal is the latest example of the widespread recognition the young Barcelona forward continues to attract across the footballing world.
