It is because with matuidi you can see he is just a limited footballer... but Bernardeschi showed a lot of proficiency in the past... so his problem is totally mental.
The infuristing thing... is that he has gone to total waste.
lets see for example the dybala case. He came here and in his frist 2 years he was a joy to watch...then it came his hungo over seasons where he looked like a shadow and now he returned to te the player he was.
On the other hand, Berna was promising in Viola, came here and banged some good asists and goals with few mins while looking stellar.... and suddenly the next season onwards he turned into a brainless monkey. Is a case for study to be honest.... because he is definitely not talentless, but man his decition making as of late is atrocious.Total lack of a north.
