4. Marcos Rojo (Sporting Lisbon)
Another useful defensive signing for Liverpool’s unreliable backline could be Sporting Lisbon’s versatile Argentine Marcos Rojo. The 24-year-old has also been linked with Arsenal, but could be ideal for Brendan Rodgers as he looks to add depth at both centre-back and left-back. Rojo has certainly proven himself to be a top talent, and looks ready to test himself on the bigger stage of the Premier League. Although Reds fans will no doubt be crying out for bigger names, Rojo may well be one of the best bargain deals currently available on the transfer market.
