And that's two back!
A clipped ball into the area from deep, Mahrez meets his header on the run, steering it back towards Haaland.
The striker throws himself into the ball, powering a header past Lloris.
What a game this is.
One back!
Mahrez stands up a cross from the right, aimed at Grealish however it results in a scramble, with Lloris rushing off his line but failing to claim the ball.
It falls to Alvarez, who calmly steers the ball into the net.
Exactly the second half start City needed.
