Rodgers admitted he has been delighted with the form of Liverpool's new No.9, who also played a major role in Luis Alberto's opener after his attempted chip cannoned against the crossbar before his fellow Spaniard tucked home.
"I thought he was excellent again tonight," Rodgers told liverpoolfc.com. "When you watch him, his movement is outstanding. If you look at the movement for the second goal, he made his first run when Stewart Downing had the ball.
"The line was blocked for him and he made a double movement to come in again. Obviously he was there to finish. He's a goalscorer, that's the reason we brought him in.
"It was a lovely chip that hit the crossbar [for Alberto's goal] and it eventually came out, and we got a goal from that as well.
"He's a really exciting player and in and around the box he can make things happen. He works his socks off as well. He's done very well over the course of pre-season."
