Vincenzo Montella was left exasperated with referee Luca Banti after he failed to dismiss Rodrigo De Paul just two minutes before the Udinese winger netted the winner in a 2-1 defeat of AC Milan.
The Argentinian midfielder caught Mattia De Sciglio with a crude tackle in the 71st minute and only received a yellow card, with the Milan full-back forced off injured shortly after.
"The De Paul situation added insult to injury," Montella Mediaset Premium. "As well as it being a red card, we ended up down to 10 men with an injured player and didn't have time to make the substitution. What can you say about that foul? It seemed a clear red.
"At the same time, we were naive; we gave the ball away and left ourselves open in that situation.
"We did something similar in Turin [a 2-2 draw against Torino] and you pay for that at this level. We hope it'll help these young players to grow and learn."
