Javier Mascherano believes Liverpool will have a good chance of upsetting Manchester United if they can replicate their Real Madrid display.
The Reds put the Primera Liga giants to the sword in midweek with a 4-0 romp at Anfield on Wednesday to emphatically book their place in the quarter-finals of the UEFA Champions League.
Mascherano believes Liverpool were at their very best against the Spanish champions due to their superb work rate in pressing Real throughout the 90 minutes.
Liverpool had been serious contenders to secure their first Premier League title earlier this season before a dip in form allowed United to move top, meaning they can ill-afford to drop any more points at Old Trafford this weekend.
See what happens
"We have to go to Old Trafford and win so we will see what happens," said Mascherano.
"But if we play like we did against Real, it will be difficult for any team to beat us.
"It was a fantastic display. We were pressing all the time and didn't let them play."
