Italian referees have always been known as the best in the world, from Colina to Rossetti and now Rizzoli but yet another good and young Italian referee.
Tagliavento called a penalty with ten minutes to go and he got no complaints from anyone especially Antonio Valencia who had committed the foul.
The two yellows he gave were correct and probably nothing else deserved a card.
European referees are always criticized by English clubs and players for calling fouls that are too soft but Tagliavento did very well by letting things go and not being whistle happy.
Very solid performance but I think he did miss a foul on Park in the second half which was probably of bad positioning or being blocked by another player.
