From day one, there appears to have been a problem brewing between Jurgen Klopp and Daniel Sturridge. Now, it appears that problem has reached breaking point.
Liverpool's new manager was forced to wait several weeks before he was able to call on Sturridge as he recovered from a tricky knee injury sustained under Brendan Rodgers' reign.
He return and thanked Klopp for his patience with two goals against Southampton, but it wasn't long before the England international was back in the treatment room.

Klopp appeared frustrated with Sturridge in press conferences, telling his striker that he would need to learn the difference between pain and serious pain. According to the Sunday Mirror, that frustration has now boiled over.
The newspaper claims that Sturridge is now facing a fight to save his Liverpool career and could be sold if a club comes in with an offer of £25million. Klopp has been left unconvinced by the striker since his arrival at Anfield and no longer feels he can invest the time and effort in him.
It is not an ideal situation for anyone at the club and officials must surely recognise that he remains the best striker on their books.
Indeed, Sturridge has scored 44 goals in 72 matches since signing from Chelsea, but he has missed more games through injury than he has played and that has left many convinced that he is no longer worth the trouble.
He has played just 106 minutes of football this season and, again, was deemed unfit to take part in Friday's FA Cup fixture against Exeter City.
There is a worry that if they continue to wait for him to get fit, his transfer value will dimish alongside his footballing ability. Sell him now and they can still make a significant profit on their original £12m outlay.
