Jurgen Klopp inherited a Liverpool squad in dire need of inspiration when he took over in October 2015.
The German, who'd recently called time on his stint at Borussia Dortmund, was the best manager on the market but was going to need several transfer windows to get the Reds outfit challenging once again - and he certainly didn't waste any time.
Few players he took on remained part of his plans and he ruthlessly set about moving players on, some of whom had only recently joined under previous boss Brendan Rodgers. For years the German was able to enjoy a relatively low net spend and in his first summer he bought in the likes of Gini Wijnaldum and Sadio Mane, but for little outlay once sales were agreed.
