Ex-Liverpool star Moreno believes Atletico will suffer a lot at 'tight' Anfield

Liverpool's defence of their Champions League trophy has come under threat after their 1-0 defeat to Atletico Madrid in last week's first leg at the Wanda Metropolitan, but Alberto Moreno is not overly worried for his former team.

Diego Simeone’s side travel to Merseyside next month having won 1-0 courtesy of Saul Níguez’s 4th-minute goal in Spain.

The result puts them in the driving seat for the second leg, with the narrow advantage sure to be something they will use to their advantage.

But Jurgen Klopp's Reds haven't tasted defeat on Merseyside in continental combat since losing 3-0 to Cristiano Ronaldo'sReal Madrid in October 2014.

Moreno believes his former side will turn up the heat on their Spanish opponents in front of a passionate and vocal Anfield crowd.

The left-back, who played 141 games for the Anfield club before departing last summer, hinted that he reckons Simeone’s side will buckle under the pressure like so many previous sides have.

“I know how tight Anfield is and it's clear that Atletico will suffer a lot,” he told La Vanguardia ahead of the second-leg.

Now at Villarreal, Moreno predicts that the tie will stay close until the end, although he gives Liverpool 'more options to pass,' he says that in a single game and with a tight 1-0 in the first leg, 'anything can change'.

There could be some tetchiness to the second leg after Madrid's players were reportedly left angry and surprised when Klopp accused them of play-acting in their 1-0 victory.
