UEFA have opened disciplinary proceedings against Pedro Neto after his ball-boy altercation towards the end of Chelsea 's Champions League loss to Paris Saint-Germain . With the Blues 4-2 down in injury-time, the ball bounced out of play and Neto attempted to retrieve a fresh one off a ball boy at the side of the Parc des Princes pitch. However, the ball boy hesitated and refused to give the ball immediately to Neto, before he seemed to motion to throw it away.
