Manchester City manager Pep Guardiola could take a leaf out of Ruben Amorim's coaching book in the Manchester Derby on Sunday.
Guardiola finds himself with a selection headache going into the clash against Manchester United, as he only has three fit defenders to select from.
Kyle Walker, Ruben Dias and Josko Gvardiol are the only senior defenders available for selection while young Jahmai Simpson-Pusey is also available.

Guardiola has now revealed he could look to use wing-backs on Sunday, similarly to what Amorim's uses with his 3-5-2 formation.
"We have three and we will see what happens today and tomorrow," the City boss said, as per Manchester World.
"I need players. We have three and we will see what happens today and tomorrow.
"Maybe some winger has to play as a full-back or Matheus [Nunes] can play as a full-back, or maybe can play five at the back with wing-backs as wingers.
"We are thinking what to do with a situation with just three central defenders."
Amorim has already got the better of Guardiola this season after City lost 4-1 to Sporting Lisbon in the former's penultimate game in charge.
