Liverpool full-back Alberto Moreno produced a magnificent Man of the Match performance as the Reds thrashed Bayern Munich 3-0 in the pre-season Audi Cup on Tuesday night.The 25-year-old Spaniard has witnessed his career go backwards since signing for £12m from Sevilla in 2014.Moreno made just two Premier League starts last season after falling behind makeshift full-back James Milner in the pecking order.Until last night, he looked destined to be sold over the summer following the recent £10m signing of Hull left-back Andrew Robertson.Moreno has been widely criticised by Liverpol fans on social media in recent seasons, and has even bared the brunt of a number of Jamie Carragher tirades.Facing one of the best teams in the world, Moreno was unquestionably superb as he bombed up and down the left wing."It was a really good game from Alberto, that's why we kept him on, because every second he was playing better, he was more present," Klopp said.He recorded an assist for new teammate Mohamed Salah and was the number one trend on Twitter in the UK on Tuesday night.Legendary Liverpool left-back John Arne Riise heaped praise on the Liverpool outcast on Twitter and suggested that it could be a turning point in Moreno's career.Renowned for his traction engine of a left foot, the retired Norwegian defender made 348 appearances for Liverpool during a seven year spell at Anfield.Riise admitted to having doubts about the Spanish international but offered some kind words of encouragement in an exchange of tweets which went viral amongst Liverpool supporters.

Are Liverpool fans, including John Arne Riise, getting a little bit carried away with one excellent display?

The Reds are due to face Spanish giants Atletico Madrid in the Audi Cup final tonight in Munich.

Jurgen Klopp's side will then face Athletic Bilbao in Dublin on Saturday before returning to the UK in time for their Premier League opener against Watford next weekend.

Liverpool have endured a frustrating summer in the transfer market but are still trailing wantaway Southampton captain Virgil van Dijk.

The Saints are unwilling to sell but have forced the Dutch defender to train on his own because he is "psychologically not 100 per cent" according to his manager.

Klopp has however captured the £37m club record signing of Roma winger Mohamed Salah.

The Egyptian winger has certainly impressed in pre-season and you would imagine that Premier League defences won't be looking forward to halting him and Sadio Mane.
