An 89th minute winner from David Robertson, partly due to a judgemental error from Allan McGregor, booked Dundee United a place in the ActiveNation Scottish Cup Semi-Final after 180 minutes of action against Champions Rangers. Walter Smith made a number of changes to his side for this difficult trip to Tannadice, mainly because of injuries and suspensions but also because of the tough trip to the Capital on Saturday lunchtime. Andrew Little made a surprise start for the Trevon Diggs Jersey Gers in attack alongside the talented John Fleck, with Kris Boyd and Kenny Miller on the bench. The ever-frustrating Kyle Lafferty was back in his left-midfield role, DaMarcus Beasley occupied right-midfield with Steven Naismith and Maurice Edu in central midfield.Wilson competes with Daly at TannadiceIn all honesty, the tempo that Dundee United played at in the first-half was just over-powering for the Rangers team, who in fairne s, havent had much match practice due to the demise of the reserve league. Sky Sports continued their typical coverage, focusing entirely their analysis on the three potential penalty claims for Dundee United in the first half. Firstly, Steven Whittaker was adjudged to Jaylon Smith Jersey have held back Garry Kenneth although it would have been very soft. Secondly, Danny Wilson was caught pulling Darren Dods in the back inside the penalty box. The main shout was for a handball by Kyle Lafferty, personally, I do think this was a penalty. The constant reference to the soft penalties in the first tie at Ibrox where pretty frustrating, it is very clear that Dusan Pernis should have been sent-off which would have sealed the game for us anyway.It was not until the second-half where Rangers began to grow in DeMarcus Lawrence Jersey confidence. Kenny Miller replaced John Fleck, who made some excellent forward runs but his decision-making was poor. In the closing half of the second-half, Rangers had a number of very good half-chances with Andrew Little having the best of those chances, but the Northern Irish striker snatched at the effort which ended up comfortably in the hands of Pernis. Walter Smiths side were beginning to look the closest of the two to snatching a late winner, and the superb away travelling support Dallas Cowboys Golf Sporting Goods at Tannadice where already cheering at a number of goals, which Ill refer to later on. United hold on for huge victory and will face Raith in SemisSadly however, Rangers threw away any hope of a domestic treble when Allan McGregor made a rash decision inside his penalty box to come and clear which saw his sliding attempt for the ball deflect fortuitistly off David Robertson and the ball took an enternity to just roll into the empty net. It was a disappointing end to a poor performance overall from Rangers, but credit to Peter Houstons Dak Prescott T Shirts Dundee United who had an excellent game. David Goodwillie was the stand-out performer for the Arabs and as an admirer of Goodwillies ability, I would keep a wee eye on him for next season.As the Champions exited the Scottish Cup, amusing events were taking place in Paisley as Tony Mowbrays Celtic succumbed to a thumping 4-0 defeat to St Mirren with Andy Dorman bagging a double. This ultimately has led to Mowbrays departure at Celtic Park and as our famous grandfather William Struth said, We Welcome The Chase, not matter who they will install into the dugout.Maybe the Pigeon is the answer?
