Manchester City moved back to the top of the Premier League with a hard-fought victory over neighbours Manchester United at Old Trafford.
Second-half goals from Bernardo Silva and substitute Leroy Sane took the defending champions a point clear of Liverpool with three games remaining.
After an edgy first half Pep Guardiola's side took control when Silva cut inside Luke Shaw and found the bottom-right corner.
Sane's goal 12 minutes later made the result comfortable, with the Germany winger firing a shot through United keeper David de Gea.
Jesse Lingard missed United's best opportunities, firing wide with a first-half volley and missing the ball when presented with an open goal after the break.
Ole Gunnar Solskjaer's team remain sixth in the table, three points from a place in the top four and Champions League qualification.
