They sent their defenders forward as it looked they would lump the ball into the box.ENTER GIVEAWAYBut Christian Norgaard came short for the ball and he played a lovely ball to Sergi Canos, who got in behind Liverpool's defence.The Spaniard crossed to Ivan Toney, who helped the ball on for Ethan Pinnock, who lost his marker to convert at the back post.Watch the goal below:

What a set-piece routine that is. Liverpool were completely caught cold.

That was Pinnock's first goal in the Premier League. He was playing non-league football with Forest Green Rovers just four years ago.

Brentford's lead didn't last long, though.

Jordan Henderson swung a ball into the box three minutes later and on hand to convert was Diogo Jota to level the scores.

Jota had a golden opportunity to grab his second and give his side the lead just before the break.

The ball fell to the Portuguese inside the box after Curtis Jones' deflected strike hit the post.

He fired an effort at goal but David Raya produced a miraculous save to deny the Liverpool forward.
