Manchester City defeated Chelsea 1-0 at Stamford Bridge on Thursday, moving to within five points of Premier League leaders Arsenal. After a poor first half from the champions, substitutes Riyad Mahrez and Jack Grealish combined to give Pep Guardiola's men the win. Chelsea battled well, but injuries to Raheem Sterling and Christian Pulisic and a missed opportunity for substitute Lewis Hall hindered their efforts to equalize. Despite Chelsea's strong performance in the first half, City's improved performance and depth on the bench led to their victory.
