A goal by Philippe Coutinho just before halftime gave Liverpool some insurance in their Europa League tie against Manchester United.

The goal meant United would have to score three unanswered.

"Phil had a genius moment," Klopp said. "It was a brilliant moment and it decided the game tonight. He had a lot of good moments and he had a big chance before the goal. It was brilliant what he did. It was unexpected. It was a perfect goal."
