Liverpool took themselves to second in the table after they beat Everton 1-0 in a feisty Merseyside derby.

Sadio Mane's late winner in the 94th minute secured a well deserved three points for the visitors, who helped continue Everton's poor derby record at Goodison Park.

Substitute Daniel Sturridge's weak effort somehow rebounded back off the Everton post, only to find it's way straight into the path of Senegal international Mane, who reacted fastest to bag his eighth goal of the season.

There were few chances before the end, with Roberto Firmino coming closest during normal time, only to be denied excellently by substitute keeper Joel Robles.

The result is a huge one for the Reds who closed the gap on leaders Chelsea, but for Everton it was another disappointing result in what has been an inconsistent season so far.

The Toffees failed to build on the momentum of their victory over Arsenal last week and will remain in ninth position for Christmas.

Both sides can take plenty from the game, though, as can we. Here are five things we learned from the fiery derby ...

Klavan's Your Man

Estonian Ragnar Klavan had Romelu Lukaku in his pocket all evening, giving the big Belgian little sight at the Liverpool goal.

Klavan, who was chosen ahead of Brazilian Lucas, was both composed whilst aggressive at the back and dealt well with the physicality of Lukaku throughout.

His partnership with Dejan Lovren looked solid and could be one Jurgen Klopp can utilise going forward.

Everton's Energy

Everton boss Ronald Koeman demanded more fire from his Everton players and that's exactly what he got.

Everton came out all guns blazing for the first half an hour, causing Liverpool all sorts of problems, and while they may have run out of steam during the second half, the Toffees effort cannot be faulted.

Despite the result, if they can take that attitude going forward, their form should improve.

Money Well Spent

Many questioned the fee Liverpool paid for Sadio Mane during the summer, but boy has he showed why he was worth it.

The man, who was signed from Southampton for £30 million, got his eighth and most important goal in a Liverpool shirt this season to hand his side a memorable victory over their bitter rivals.

Energetic, skilful and, as demonstrated so brilliantly against Everton, instinctive, Mane is a well rounded forward who could prove to be the signing of the summer come the end of the season.

Passion and Pride

Just look what it means to them. Both the players and Jurgen Klopp are clearly ecstatic with the three points. Togetherness like that is a trait we haven't seen in a Liverpool side for a long time, which makes them a real contender for the title.

They didn't play their best either, but that's the trait of title contenders, grinding out results when you most need it.

An Absent Barkley

In his defence, Ross Barkley's effort - much like all his team mates - cannot be faulted. But one thing that can is the quality of his final product. Too many times in the opening half an hour did the Englishman find himself in promising positions, only to fluff his lines and lose the ball.

The young midfielder is certainly having a hard time of it as of late, and his frustration showed late on when his poor challenge on England teammate Jordan Henderson could have resulted in a red card.

Barkley needs to be careful or he could find himself slip from the Everton side. as well as the England one.
