Guardiola benches Walker, demands inverted full-backs

Manchester City manager Pep Guardiola says Kyle Walker cannot play as an inverted full-back, leading to his benching in recent matches.
Guardiola prefers full-backs who invert and join midfield to control possession, a style Walker cannot replicate.
Though Guardiola has faith in Walker, his skills do not fit City's current system and strategy.
With a Premier League match against Southampton approaching, Guardiola must decide whether to continue benching Walker.
City aims to close the gap with league leaders Arsenal with a win against Southampton.
