Dejan Lovren has committed his future to Liverpool by signing a new long-term contract that will keep him at Anfield until 2021. 

The 27-year-old moved to Merseyside in 2014 and has been a regular in the side. His form though has been questionable.

The defender is more than capable of stringing together a decent run performances but has also had some shockers in a Liverpool shirt.

Last weekend's 2-1 loss at home to Crystal Palace is evidence of that.

But Jurgen Klopp has seen enough to reward Lovren with a new contract. He has been a key member of Liverpool's team over the last few years, making 105 appearances since joining from Southampton.

"I think I am the happiest guy [in the world] today," he said, according to BBC Sport.   

"It was always my dream to stay as long as possible at one club that I love - and that is Liverpool." 

The fact that Lovren's new contract is worth a staggering £20 million over the next four years may be part of the reason he's so happy today. 

Broken down, the Croatian's new deal has him earning up to £100,000-a-week.  

This puts him up there as one of the highest earning players in Europe. In fact, there are a number of huge names who are currently earning less than the Liverpool defender.   

Here are just 12 of them:

Sadio Mane (Liverpool) - £90,000

Laurent Koscielny (Arsenal) - £90,000

Nemanja Matic (Chelsea) - £90,000

Santi Cazorla (Arsenal) - £90,000

Serge Aurier (Paris Saint-Germain) - £85,000

Gary Cahill (Chelsea) - £85,000

Thiago (Bayern Munich) - £77,000

Toby Alderweireld (Tottenham) - £75,000

Christian Eriksen (Tottenham) - £75,000

Marcos Alonso (Chelsea) - £70,000

Giorgio Chiellini (Juventus) - £57,000

Isco (Real Madrid) - £50,000

It's incredible to see that Lovren, who has helped his team keep seven clean sheets from 25 games in the league this season, is earning more than someone like Chiellini, who is seen as one of the best defenders in Europe.  

Klopp will be hoping his new high earning defender can help get Liverpool back into the Champions League next season, otherwise, the money they're paying him won't seem justified.
