Hes not underrated on here, its just some of us don't treat him as if hes already realised his potential. Hes got a long way to go before he can be considered to be as good as people like you are making him out to be, and this ejaculatory policy towards him is only complicating that. He needs to remain grounded and focused to become the player we all know he can be, unfortunately this media frenzy and thrusting him into the position of national wonderboy is only making things harder for him.
I am not a pedant, there are others on this site better suited to that pantomime role, however, no one has said he has realised his potential. Instead, you described him as not 'remotely close' be being a great player - this type of description makes him sound like januzaj at Manure. I ask again - which 20 yr old in world football has achieved what he has and has his potential? None - this alone suggests he is a unique talent who is on the VERGE of something spectacular.
CELEBRATE him whilst we can and whilst he continues to score goals and play well. CELEBRATE and REJOICE.
