Jordan Henderson admits Liverpool players were unhappy with referee Paul Tierney against Manchester United.

The Reds had a great chance to score before half-time when Sadio Mane was put through by Thiago, only for Tierney to blow his whistle five seconds early into the one added minute from the first period.

"We weren't happy about that as you can imagine. Strange very strange," the England midfielder complained to Sky Sports.

"He's through on goal if he doesn't blow that. I don't know. We were frustrated at half-time, but there was plenty of time for us to score another goal but lacked quality in that last bit."
