Federation Internationale de Football Association refereeing supreme Massimo Busacca on Monday scolded Juventus skipper Gianluigi Buffon for saying ref Michael Oliver should have thought of the moment in the match when he gave a 92nd minute penalty for Real Madrid that allowed Cristiano Ronaldo to win the tie 4-3 on aggregate after Buffon was sent off for protesting.
Juventus were winning 3-0 after losing the first leg by the same score, but their hopes of a famous victory were spoiled when Oliver awarded a stoppage-time penalty to Madrid.
Now Uefa has acted on the unacceptable abuse, issuing a statement last night saying: [We] strongly condemns the abuse directed at Michael Oliver and his wife.
It has also emerged that police are investigating text messages sent to Lucy Oliver as they face the backlash of his penalty decision in the last minute of the Champions League quarter final.
"We have been in contact with them to offer our support and we trust the relevant authorities to take action against those individuals who have behaved inappropriately both on and off social media".
Professional Game Match Officials Limited (PGMOL), who are responsible for English referees, have also stood by Oliver as he prepares to officiate West Ham vs Stoke City on Monday.

Speaking to Sky Sports , Salah said: "If you had a choice, then of course the Champions League ". I can not lie - it is in my mind.
TV replays suggested Oliver made the right call, yet Juve captain Buffon led the protests on the pitch and was sent off for his aggressive response towards the referee, with his post match comments adding fuel to the annoyance simmering among Juve supporters.
On Saturday, Buffon said in an interview that he would repeat the comments all over again but in "more civil" language.
"We are aware of threatening messages being posted on social media", a Northumbria police spokesperson told BBC Sport.
'Neighbourhood officers are in touch with the victims in this case to offer them support and ensure any further offences are reported to police'.
Italian referees' chief Marcello Nicchi has said that Juventus goalkeeper Gianluigi Buffon was wrong to criticise English official Michael Oliver. Big admirer of Buffon but his behaviour since has been inflammatory and out of order. Understand the emotion but time to defuse it, Gianluigi'.
