Input: Ronny Deila bemoaned the refereeing blunder which cost ten-man Celtic side a crack at a rare domestic treble. Virgil van Dijk's sublime 16th free-kick gave the Parkhead side a dream start to their Scottish Cup semi-final clash with Inverness. But the Parkhead side were denied a clear penalty and the chance to go 2-0 ahead before half-time when additional assistant Alan Muir failed to spot a goalline handball from Josh Meekings. Ronny Deila was angry at the referee's decision to now send off Josh Meekings and award his side a penalty Celtic's anger was further fuelled when McLean - rightly - sent off Parkhead keeper Craig Gordon for clattering into Marley Watkins in 53 minutes, Greg Tansey equalising from the spot.Ronny Deila was angry at the referee's decision to not award his side a penalty and send off Josh Meekings for a handball on the goal lineInverness went onto win 3-2 after Craig Gordon was rightly sent offCeltic's hopes of a domestic treble were dashed at Hampden ParkCLICK HERE for all the latest Celtic news
