City are back to winning ways in Premier League with a 2-0 win over Brentford.
Mahrez gave them the lead in the first half, curling in a brilliant penalty into the net after Sterling was fouled by Rasmussen.
City dominated the second half as well and got their reward.
Raya sliced a clearance at Sterling and saved his shot, but De Bruyne was on hand to bury the rebound.
Rodri almost rounded it off in style with a long-range effort, but he was denied by Raya.
