To be fair, he hardly was regularly played last 2 seasons (3-4 games back to back for 90 minutes) he either was a sub or been subbed before the end of the game.
His talent is clear (made the difference in key games with us) was our best player against Atletico along with Ronaldo when we really needed to win that game.
He lacks confidence IMO, I always found it strange with our managers when they insist on playing players regularly (all freakin season) when they’ll in a bad form ala Sandro, yet they hardly give time to players like Berna !
