Of all the players around the globe, for me Chiesa is the player Barcelona should be seriously interested in.
His style would give Barcelona exactly what they miss right now. Someone who is aggressive with their play, looks to run in behind, looks to go past defenders and has an eye for a goal. At the young age of 23 he has already played in huge games and the way he plays is always the same showing he is mentally tough and nothing ever seems to phase him.
The question of course is finances and whether Juventus will let such a promising young player leave, but I honestly believe he will become one of the best players in the world and he is someone Barcelona need to rejuvenate and adapt their style of play.
