Liverpool have typically had quiet January transfer windows under Jurgen Klopp.
So it was a shock for a lot of supporters when the Reds splashed the cash to bring Luis Diaz in from Porto, with the deal potentially worth £49 million.
At one stage, Diaz looked set to be followed by Fulham's Fabio Carvalho, as Liverpool had agreed a fee for the youngster. Carvalho was poised to head back to the capital on loan for the remainder of the term, but the deal collapsed at the last minute.
