Liverpool assistant head coach Pep Lijnders has described Liverpool's attackers as being "like raptors from Jurassic Park" after the 5-0 hammering of Manchester United.

The Reds have been potent this season, their tally of 41 goals in all competitions bettered only by Bayern Munich (60) among teams from Europe's top five leagues.

Mohamed Salah has been responsible for 15 of those goals, making him the second-highest goalscorer among Europe's elite this season behind Robert Lewandowski (17).

Sadio Mane and Roberto Firmino have six each, while, and Diogo Jota – who scored against United on Sunday – has four to his name.

Each of Liverpool's forwards have been in fantastic form and Lijnders puts that down to Jurgen Klopp's men going back to basics.

"I think it has to do with the way we are playing," he said during a news conference on Tuesday previewing the midweek EFL Cup last-16 tie with Preston North End.

"It's the whole package that means our front players get into good positions. The front three look like raptors in Jurassic Park!

"We haven't changed anything. Sometimes improving is going back to basics. Players needed a break after a few intense and emotional seasons."

Liverpool have scored 41 goals in all competitions this season

With his hat-trick at Old Trafford, Salah has now scored in a club-record 10 successive matches for Liverpool in all competitions.

The Egypt international, who surpassed Didier Drogba (104) as the highest-scoring African in Premier League history with 106 goals, is expected to be rested against Preston.

Takumi Minamino scored twice and Divock Origi was on target as Liverpool swept aside Norwich City 3-0 in the last round and both players are in line to start again at Deepdale on Wednesday.

"We are used to making changes," Lijnders said. "We have to do things the right way by training and recovering correctly.

"That's what I like about us – we prepare at the same level no matter who the opponent. We have to show our fans that same hunger and desire.

"Origi is the top scorer in this competition. He is a world-class finisher and is looking sharp, as is Minamino. Last season went to show that we need all of our players.

"They all have to show the right mentality and be ready. They have to stay patient and keep training hard."

Lijnders confirmed James Milner will miss Liverpool's next four matches ahead of the international break with a hamstring injury sustained in the win at Old Trafford.

Naby Keita also came off in that game following a strong challenge from Paul Pogba, who was shown a red card, but Liverpool's assistant was able to provide a more positive update on the midfielder.

"Naby has a bruise in this moment, which we are assessing day by day," Lijnders said.

"Thankfully his leg wasn't planted, but it's still a painful one. It's looking good. Fabinho will also be monitored daily and may return next weekend."

Liverpool travel to Preston aiming to keep alive their good record against lower-league opposition in the EFL Cup, having progressed from 16 of their past 17 such ties.

"Our priority is to put on a good display," Lijnders added. "That is the case from the start of the season until the end.

"Our game needs freshness and we want the opponents to feel our attack. The only way we will be able to properly press is to rotate.

"We are taking it game by game and are hoping to maintain our consistency."
