With central defenders Phil Jones and Jonny Evans already injured, Louis van Gaal now has an uncontrollable nightmare on his hands with the suspended Chris Smalling and injured Marcos Rojo, leaving the Dutchman's options under extreme restrictions.
Manchester United had no defensive issues ahead of the Manchester derby but Chris Smalling's ludicrous actions and a fierce challenge on Marcos Rojo have now got a disaster to deal with.
Smalling picked up his first booking of the match approximately 25 minutes in when he needlessly and purposely blocked Joe Hart from kicking the ball out of his hands to the free Sergio Aguero and Stevan Jovetic who would most probably counter attack from the move.
At the time, the English centre-half's actions seemed intelligent and clever, but they weren't seen as impressive when he picked up his second yellow card of the game just before half time, with a schoolboy error, sliding in carelessly on James Milner.
So on came Michael Carrick, playing the rare and unusual role of centre back for the remainder of the game. However, the midfielder did not expect to be joined by youngster Paddy McNair halfway through the second half after Marcos Rojo picked up a clearly visible nasty injury in which he was treated with oxygen for.

"When you see what you have done with 10 men against 11, you can be very proud"
After the game, the Argentine was taken to hospital where x-rays showed that the 24-year-old had dislocated his shoulder to the dismay of boss Louis van Gaal who praised the effort of his 10-man-squad after the game.
"When you see what you have done with 10 men against 11, you can be very proud," said the Dutch coach. "We have a defensive issue with so many defenders injured. We seem to be playing with a different defence each week."
Rojo will certainly miss the next game against Crystal Palace next week, however there is no set date for the Argentinian's return.
With a landslide of injuries for United, van Gaal may try out the compatibility of Tyler Blackett and Paddy McNair in the next fixture instead of playing the out of position Michael Carrick in the back line.
