MANCHESTER, England: Kyle Walker is set to have only limited game time at Manchester City for the rest of the season because manager Pep Guardiola said the England right back is ill-equipped to play in the team’s new system. Guardiola has been playing a three-man defense, pushing one of the full backs in a central-midfield role alongside Rodri. That has been John Stones in recent weeks, meaning Walker — who isn’t as technically strong on the ball — has mostly been a substitute despite being a key member of City’s success in recent years.
