Pep Guardiola has explained the tactical decisions he considers when whittling down his five Manchester City centre-back options to two starters in each game.
Guardiola has five fit centre-backs at present, but only two starting spots in his line-up, although he has been able to play another at full-back while Kyle Walker is out.
Manuel Akanji has started well since signing in the summer, while Nathan Ake is in his best form as a City player. The pair are competing with Ruben Dias, Aymeric Laporte and John Stones for a place in Guardiola's line-up, with the manager insisting on Friday that all five options could play every game if they had to.
