Having watched Barcelona's last four matches in the Champions League, I don't believe it is extreme to say that someone needs to take Sergio Busquets aside (coach Josep Guardiola, captain Carles Puyol or one of the backroom staff) and tell him a few things about how to carry oneself on the pitch. The Spanish international was again guilty on Wednesday of exaggerating a foul as he helped to get Thiago Motta sent-off in Barca's Champions League semi-final elimination at the hands of Inter Milan.
