It was an incredibly difficult period for Danny Ings at Liverpool.

The 27-year-old made the move from Burnley in 2015 after scoring 37 goals in two seasons for the Clarets. He actually got off to a decent start, scoring twice in his first five Premier League games for the Reds. Then, though, disaster struck. He ruptured his cruciate ligament, and he would go on to miss 50 games for the team before coming back into the side on the final day of the 2015/16 campaign.

It wasn't much better during his second full season either. He made just two appearances in the whole campaign, missing 35 matches following knee surgery. He couldn't have had much worse luck.

In the end, he moved to Southampton in July last year, initially on a loan deal with an obligation to buy, making just 25 appearances in three full seasons at Anfield through no fault of his own.

Since joining the Saints permanently, though, he has hit the ground running. In 12 starts this term, he has eight goals, as well as one assist. Incredibly, he has had a hand in more than half of his team's goals in the Premier League as they struggle at the foot of the table. He has been his team's biggest danger man by far, and one can only imagine how much more dangerous he could be with better service.

Although it didn't really work out for him during his time upon Merseyside, it can be argued he could still do a job for Liverpool now. Roberto Firmino is undoubtedly Liverpool's first-choice striker - even if he has scored just four goals in all competitions - but behind him, there is just Divock Origi. The Belgium international has just five goals this campaign in 18 appearances, and he has often been used at left wing as cover for Sadio Mane as well. Although he did bag a brace against the Toffees, he appears to be the first alternative for the Senegal international. What happens if the 27-year-old were to get injured?

Given his Premier League experience and ability to score, as he is showing at St Mary's, Ings would have been a good option as an alternative for the Brazil international. They may have got £20m for him in the previous transfer window, but with so many games to come, they could do with him as part of the squad now, especially as they were so quiet themselves during the summer. Everything is easier in hindsight, but this is maybe one decision Klopp got wrong.
