The 2013/14 season must seem like a lifetime ago for Liverpool striker Daniel Sturridge. Throughout that remarkable campaign on Merseyside, the England international was sensational, scoring 21 goals in 29 league appearances.
With Sturridge and the unpredictable yet brilliant Luis Suarez leading the line at Anfield, Liverpool had one of the most feared strike forces in Europe at their disposal.
Suarez would go on to complete a mega-money move to Barcelona, of course, while Sturridge has failed to come to prominence ever since.

It has been a torrid year or so for the former Chelsea man, who only featured on 12 occasions in the Premier League last season, scoring four goals in the process.
And this term has been just as traumatic for the once lethal hitman; Sturridge has only played in 25% of the club's league games so far and is yet to take to the field under the guidance of new manager Jurgen Klopp.

Needless to say, Klopp has a problem at Anfield. In Sturridge, the German coach has a proven Premier League goalscorer and a wonderful striker at his disposal, but he just can't rely on him to maintain his fitness.
At 26, Sturridge should be approaching the prime of his career, but he has bigger issues to contend with right now. It's a huge shame, of course; the versatile forward has so much to give and will no doubt be desperate to prove his credentials once again.
But, Klopp has to deliver results on the pitch. Brendan Rodgers knows only too well that the Liverpool hierarchy won't accept failure, so Klopp has to be ruthless in his pursuit of success.
There will come a time when he will have to replace his struggling forward. With the January transfer window on the horizon, some fans may well feel that the revered coach should act as he goes in search of securing a place in the top four this season.
Ultimately, the club can ill afford to carry passengers if they are going to progress. You wouldn't blame Klopp for remaining patient with Sturridge, but he'd be foolish not to move forward over the coming months.
If the right striker is out there, then Klopp should probably act. A top-class striker, who manages to stay injury free, could help the club climb the table. The former Borussia Dortmund boss hasn't been in the job long, but he will surely be aware that a couple of January additions could make all the difference for him and his side this season.
