United staged a tremendous recovery from two goals down to deservedly hold last season’s Under-20 League Champions. By Peter Rundo A highly controversial penalty midway through the first half put the visitors in the ascendancy. Tangerines’ defender Adam Harwood was harshly adjudged to have impeded Paul McMullan and Filip Twardzik slotted away the spot-kick. Although it had been even enough earlier and a Darren Petrie lob came off the top of the crossbar, Celtic dominated after getting their noses in front. Indeed, Jackson Irvine blocked team-mate McMullan’s shot to prevent a second 35 minutes and would have redeemed himself two minutes later but for a terrifically acrobatic save by home keeper Marc McCallum. However, five minutes from the interval Jamie Lindsay outstripped the Tannadice defence to angle in the second from just inside the box. In an about turn in the second half, Stevie Campbell’s side, showing new found impetus, were level with just over an hour played. On 57 minutes, Celtic failed to clear their lines and Blair Spittal smashed the bouncing ball into the roof of the net from close range. Four minutes later, Petrie’s looping header from a Scott Fraser cross brought the equaliser. Dundee United: McCallum, Spark, Petrie, Telfer, Harwood, Souttar, Connolly, S Smith, Adeyemo, Fraser (Montgomery 78), Spittal. Substitutes: Zwick, Ballantyne, B Smith, Robson, Coote, Tumilty.
