Plenty of Leeds fans think they know what Garry Monk was doing in loss to non-league Sutton

Leeds United missed a golden opportunity to reach the fifth round of the FA Cup, suffering a giantkilling at the hands of non-league Sutton United.

A Jamie Collins penalty proved the difference, meaning Sutton join fellow National League side Lincoln City in the last 16 of the competition. Normally, one might think supporters of the Championship high-flyers might be angry with manager Garry Monk for naming a weakened side for the clash, and there was a little bit of that. But many are looking at the bigger picture, namely that there are just a couple of days left in the transfer window for the Whites to add reinforcements for their promotion push. https://twitter.com/awinehouse1/status/825731689607528448 Leeds currently sit fourth in the Championship table, seven points adrift of the automatic promotion places and the same number ahead of Barnsley, who sit just outside the play-off spots. However, while things may be looking rosy right now, there is a sense that there could be trouble ahead if just a couple of first-team regulars are lost to injury. That seemed to be the view of Yorkshire Evening Post journalist Phil Hay, and it's something upon which a number of Leeds supporters agree. https://twitter.com/PhilHayYEP/status/825735034653007872 https://twitter.com/BenIrwin91/status/825735023793995776 https://twitter.com/lliambrocksom/status/825736001280737280 https://twitter.com/ShipleyWhites/status/825736248677560320 https://twitter.com/J_MO80/status/825737675848155137 Still, while some had sympathy with Monk for showing the club's higher-ups what they need to do, others believed there may be better ways to make that point. https://twitter.com/Dave_Deane21/status/825734148832759808 https://twitter.com/JamieTwilkinson/status/825735349943033858 https://twitter.com/jhealey89/status/825735810913800192
