Iago Aspas watched enough of the FA Cup during his time in Spain to know that Oldham Athletic will travel to Anfield on Sunday confident they can cause an upset.

The Latics stunned Liverpool in the last encounter between the sides in January 2013, when Boundary Park witnessed a giant-killing of the highest order.

Matt Smith struck twice in the first half and Reece Wabara looped a header over Brad Jones to render strikes from Luis Suarez and Joe Allen meaningless and eliminate the Reds.

Brendan Rodgers' side have already locked horns with lower league opposition this season in the Capital One Cup, where they needed extra-time to see off Notts County.

Aspas is eager for there to be no such repeat of either of the aforementioned events on Sunday - and has warned against complacency in the afternoon kick-off.

"Every game here is very difficult. You only have to look at what could have happened in the Capital Cup One against Notts County," he told Liverpoolfc.com.

"It was two goals each and we had to go into extra-time before eventually getting the goal that would take us into the next round.

"That's why we can't go into the game and take things easy as that's when any team is capable of giving you a beating.

"I think that all the cup competitions are very important over here. I can remember tuning in to the two finals from last season.

"Swansea were up against a League Two side in the League Cup final and, of course, there was the Wigan against Man City game [in the FA Cup final]. They are very special occasions, especially for the supporters, and not just for the players."

Plenty has changed around Oldham since they halted the Reds in last year's fourth-round clash.

Manager Paul Dickov resigned from his post a week after the 3-2 win and has since been replaced by Lee Johnson, who became the Football League's youngest manager when he took the reins aged 31.

Smith, who proved to be a handful for Liverpool's defenders last time around, moved on to Leeds United, while a considerable number of squad players have since departed.

However, Oldham will still retain a belief that they can travel to Anfield and put up a fight, and Aspas insists the Reds must be completely focused on their own game this weekend.

He said: "The FA Cup looks to be a great competition to play in, at least from what I could see looking at it from abroad before I came to England. It is thought of highly here, whereas by comparison, in Spain we don't lend as much importance to the cups.

"It's important to take each game as it comes, starting by being as hungry as possible as we go into the Oldham game."
