Roberto Firmino admits he needs to improve his finishing with the Liverpool striker determined to take out his frustration on Newcastle United at St James' Park tomorrow.

The Brazil international wasted some glorious chances in the midweek Champions League draw with Spartak Moscow as he failed to add to his four goals so far this season.

Firmino, who was pictured crying after missing a penalty in Liverpool's previous European stalemate with Sevilla, takes nights like that to heart.

“It was an unfortunate night for our team that we didn’t manage to score the goals to get us the win," he said.

“We had a lot of chances but unfortunately we didn’t manage to finish them to get the three points. Our group is still open and we have a big chance to qualify. We’re going to fight until the end.

“I am very tough with myself whenever I miss chances to score. I want to continually improve – I want to improve my finishing, my technique and score whenever I get the chance to.

“It is important to stay positive. We have created a lot of chances to score and that’s better than not creating them. I hope in coming games and the games after them, we’ll be able to finish them and achieve victories.”

Firmino is confident the goals will start to flow now that Jurgen Klopp is able to call upon all of his major attacking weapons.

The game in Moscow was the first time this season that Firmino, Sadio Mane, Mohamed Salah and Philippe Coutinho have all started.

“It’s excellent, to play with these three,” he told Liverpoolfc.com

“It’s very important for me and for everyone. I hope that we can help Liverpool to the absolute maximum to play well.

“With Sadio and Mo, they’re giving us quite a lot of chances on goal. They’re very quick and we’re enjoying playing with the two with the speed they give us.”
