Uefa says it “strongly condemns” the abuse received by Premier League referee Michael Oliver and wife Lucy.
Michael Oliver awarded a last-minute penalty as Real Madrid knocked Juventus out of the Champions League last week and was criticised by keeper Gianluigi Buffon and some Italian media.
BBC Sport understands Lucy Oliver – a Women’s Super League referee who also officiates men’s non-league football – received threatening texts after her mobile number was posted on social media following the game.
In a dramatic end to the match in Madrid on Wednesday, Juventus captain Buffon was sent off for confronting Oliver over the 93rd-minute penalty decision.
Meanwhile, Manchester United players who performed poorly in their Premier League defeat by West Brom will be dropped for Saturday’s FA Cup semi-final against Tottenham, says boss Jose Mourinho.
The Red Devils were beaten 1-NIL by bottom side West Brom at Old Trafford on Sunday, ensuring rivals Manchester City won the title.
