The left side of Liverpool's defence remains the position that carries the most uncertainty for Brendan Rodgers.
With Jose Enrique still out with a long-term injury and Jon Flanagan naturally a right-sided defender, speculation continues as to who Rodgers will bring to Anfield next season.
In the latest twist in the rumour mill Real Madrid defender Marcelo has been linked with the Reds, while Sevilla left-back Alberto Moreno and Sporting Lisbon's Marcos Rojo have also been tipped as Liverpool transfer targets.
The one certainty remains that Rodgers has to make a signing at left-back, or stick with Flanagan down the left-hand side. The likelihood is a new face will frequent the area for Liverpool next term.
Ilori is said to be leaving Anfield on a temporary basis, spending his second season at the club out on loan - just as he did during the first. However, 33-year-old Toure and 23-year-old Coates have been tipped to leave the club on permanent deals.
While Liverpool will once again be left with four centre-back options, then, their best pairing will still not be resolved.
Martin Skrtel and Mamadou Sakho are considered Rodgers' first-choice pairing but Daniel Agger may have other ideas as he looks to force his way into the side. Croatia man Lovren, meanwhile, will also want his fair share of playing time should he make the move to Anfield.
The right flank is arguably Liverpool's least problematic defensive position now that Flanagan can make the transition to his preferred side. Alhough 29-year-old Glen Johnson is the subject of much criticism, especially from a defensive viewpoint, Rodgers appears happy to keep faith in the England man.
Flanagan will offer, firstly, an immediate stand-in should Johnson's form let the side down and, secondly, a long-term replacement, being eight years Johnson's junior.
A signing Liverpool have already made, Emre Can, can also deputise primarily at left-back, though his versatility could allow him to play across the defence.
What proved to be the Reds' problem area last season, then, looks like it will be the subject of a major revamp ahead of next campaign. Liverpool conceded 50 Premier League goals last season, but Rodgers will hope the changes made this summer will stop the leakage once and for all.
Probable Liverpool back-four A: Johnson, Skrtel, Sakho, Moreno/Rojo
