There is no point in trying to loan or sell him because at the end of the season he can sign for another club on a free. As far as I am aware his deal runs out in January 2019 so trying to get anything for him is nigh on impossible. In truth he should have been sold long before now when it was clear he is made of paper and a luxury we cannot afford to have. This is his 7th season with us and he has only managed 125 appearances in all competitions. Granted his strike rate is almost half that but having him for a few games here and there just sums up his career. The best season he ever had in terms of goals and appearances was alongside Suarez that year. He hasn't come close to emulating that season since.
In fairness to Danny though he is a quality finisher when on it. Just think Klopp marked his card early on and they never really saw eye to eye since. He doesn't get the protection anymore like he got with Rodgers where we would play to his strengths. He has to adapt under Klopp to incorporate more aspects to his game which he isn't able for. We have no other options and Klopp isn't flexible enough to switch it up so Danny will just have to keep plugging away when selected. He will certainly weigh in with a few goals this season but his time is up here and we need to get someone more reliable and better suited to the system.
