Daniel Sturridge may only be 28-years-old, but his decline at Liverpool is well underway.

He arrived at Anfield in January 2013 and soon struck a deadly strike partnership with Luis Suarez, suggesting Brendan Rodgers had found a winning formula.

Twenty-one goals in Sturridge's first full season at Liverpool was a fantastic return considering he cost the club just £12 million.

But injuries then started to take their toll. In stark contrast to 26 Premier League starts in the 2013/14 term, Sturridge made just 12 appearances in total the following season.

It was much of the same in 2015/16 (14 league appearances) and 2016/17 (seven starts), which now finds Sturridge wasting away on the bench under Jurgen Klopp.

Liverpool's manager prefers Roberto Firmino to the England striker, who appears to have lost a yard of pace and his goalscoring touch over the past few years.

Not that it's an accurate measurement of Sturridge's decline, but his pace rating on FIFA has plummeted from 89 to 76 in the space of a year. Ouch.

Sturridge's international career has suffered, too. He's made just one appearance for England in 2017 and his last goal came in November last year, against Scotland.

Harry Kane, Danny Welbeck and Marcus Rashford are now all ahead of him in the pecking order under Gareth Southgate.

And to think, Liverpool legend Jamie Carragher once insisted a fully-fit Sturridge was the Premier League's second best striker, behind Sergio Aguero.

Carragher even said Sturridge was better than Kane, which now sounds absolutely ridiculous given the latter's current form for Tottenham.

"When Daniel Sturridge is fit and firing, Sergio Aguero is the only striker who is better than him in the Barclays Premier League," said Carragher two years ago. "That's how highly I rate Daniel.

"The one thing I remember most of all from being his teammate is that he had to feel 100 per cent right mentally and physically in order to play.

"I'm a massive fan of Kane, but a fully-fit Sturridge is better.

"Daniel's problem now, though, is that he's being remembered more for injuries than goals. And he is the only man who can change that perception."

Carragher pointed towards Sturridge's injuries as his biggest problem and what he said couldn't be more true right now.

Two years on and the 28-year-old still can't string more than five games together, which is a crying shame given his potential.
