Former Liverpool manager Brendan Rodgers, who returns to Anfield this Saturday with his Leicester City side, had moves for two defenders blocked by the board when he managed the Reds.
Rodgers, who was at helm of Liverpool from 2012 until 2015, made 33 incoming signings in this period, with Philippe Coutinho, James Milner and Roberto Firmino three of his most impressive acquisitions.
In defence, left-back Alberto Moreno was signed from Sevilla for £12m in 2014, with centre halve Mamadou Sakho signing from Paris Saint Germain a year earlier. Neither player really made a positive impact at Anfield though, with Sakho leaving for Crystal Palace in 2017 after 56 appearances for Liverpool, with Moreno joining Villarreal in July after having limited playing time under Jurgen Klopp in recent seasons.
