Liverpool defender Joe Gomez was upset with Atletico Madrid's tactics for last night's defeat.

The Reds lost the first-leg of their Champions League round 16 tie 1-0 in Madrid.

Gomez made clear his annoyance with some of the less-than-wholesome tactics from Atletico's players once their early lead had been established through Saul Niguez's winner.

“European football is different," he said. "And referees are different. We have to stay patient. We had our chances to be fair, and if one of those goes in, it's a different outcome.

"We'll continue to do what we do, play with the same intensity and with our atmosphere that adds to things. We'll see how they cope with it. Until then, our focus is on the next one and when it [second leg] comes around, we'll be ready.

"It's frustrating because we're all competitors and it's annoying when you give your all and then the ref does something you don't think is right.

"We're going to compete, but if it's taken out of our hands by the atmosphere or their reactions or whatever, we don't want to let that affect the game.

"We've just got to stick to our gameplan, play our way. The atmosphere plays a part in certain moments when the crowd is jeering or booing, it doesn't help. But it'll be a different case at Anfield."
