Liverpool were in fantastic form against Everton at Anfield on Wednesday.

The Reds beat their city rivals 5-2, which is now the 18th match in a row in which they have not lost to the Toffees. By beating Marco Silva's men, they restored their eight-point lead at the top of the Premier League following Leicester's earlier victory, and they have now picked up maximum points in 14 of their 15 matches of the campaign in the league.

Not only that, but the dominant display came following a change in formation. Jurgen Klopp used a 4-2-3-1 formation for the first time this campaign, and it did wonders for the team as they put their opponents to the sword. It also brought the best out of some of players who took up slightly different responsibilities and roles.

Georginio Wijnaldum, in particular, was given the freedom to offer more offensively. He scored just his second goal of the term, and completed two of the three dribbles he attempted during the match. In the Premier League, he has averaged just 0.8 per match, which shows a significant increase. As part of a two in midfield, he was required to play a bigger role both defensively and in attack, and he rose to the occasion magnificently.

He was not the only way to offer his boss something different from his usual displays, either. Sadio Mane has been in fantastic form this term, as his 7.64 average WhoScored rating indicates, but he is more known for his goalscoring ability. Last season, he was Liverpool's joint-top goalscorer with 26 goals, but added just five assists.

However, in 2019/20 he already has seven, and two came against the Toffees. It is the first time he has contributed more than one assist in a match since March 2018. Playing in a three behind the striker, and with therefore one more man in attack, he did not need to do as much of the goalscoring and shooting himself, enabling him to offer more for his teammates instead.

They were not the only two to take up slightly different roles. Adam Lallana, for example, played in attacking midfield for just the second time this campaign and, although he couldn't hit the heights of Mane, he still played his part. What this all shows is that Klopp has a lot versatility, and he is able to mould the players to his system rather than the other way around. A manager who is able to do that is worth his weight in gold.

Meanwhile, Liverpool fans loved one man's display against Everton.
