Manchester City returned to winning ways in the Premier League and closed the gap to the top four with a hard-fought victory over in-form Southampton at St Mary's.
Raheem Sterling swept in from Kevin de Bruyne's cutback after 16 minutes as Pep Guardiola's side stamped their authority following the hosts' energetic start.
Southampton, who began the day third in the table, responded well but their efforts to draw level were hampered by the loss of striker Danny Ings through injury before half-time.
In a tightly contested second half, Bernardo Silva miscued his shot after being played in by De Bruyne, while the hosts had appeals for a penalty for handball against Sterling dismissed by VAR.
