Chelsea signing Noni Madueke has been rated ahead of Liverpool attacker Cody Gakpo.
The wingers have left PSV Eindhoven this month for England.
Saul Isaksson-Hurst, who has worked with the 20-year-old on a one-to-one basis over the last few years, told Sky Sports: "He is top, for me he is one of the best young forward players in Europe, easily.
"A lot of focus has been on Cody Gakpo at PSV because of the World Cup but Noni is up there.
"He is one of the best, if not the best, because he is so dynamic, so strong in one-vs-ones, so technically gifted, so athletic. Really, he's got the full package. Noni is an attacking wide player who likes to play on the right as an inverted winger, so one of his 'super skills' is cutting in on his left side, like Arjen Robben, and shooting from the edge of the box.
"We worked a lot on challenging and trying to develop his 'super skill' but I also talked to him about the space it opens up on his right side, on his weaker foot, which he has done a lot of work on himself over the last few years.
"You see when Robben played, defenders would overcompensate to make sure he didn't get them on the inside, but that opens up a lot of space on the outside, and we worked a lot on that, going in and then going out again, onto his weaker foot.
