Martim Fernandes (Porto)

The youngest player of the three, and arguably the one with the greatest potential, is Martim Fernandes, who has impressed many since breaking into the Porto first team this season.

In 21 Liga Portugal appearances, Fernandes has five assists to his name and at just 19 years of age, is already a key creative cog in the side.

He enjoys playing on the front foot and much like Alexander-Arnold, he is an excellent crosser of the ball, adept at delivering into dangerous zones inside the opposition's six-yard box.

No wonder he is averaging an expected assists (xA) per match figure of 0.31 in the Portuguese top flight, a hugely impressive figure considering his age.

The young Portuguese provides an option on the flanks by playing high and wide up the pitch when Porto are attacking but is also capable of adding variety by making darting runs for the centre-backs to pass to, beyond the last defensive line of the opposition.
