Wayne Bridge, Pervis or Gary Williams.
Re Gary Williams, defensively sound, crossed a good ball, and could certainly hit one as well, ask Shilts…..
Different era though……
Went with Robertson (yes, I know, bad fan), but normally Robertson is a reliable defender for Liverpool, and IMO stronger than Pervis in that respect. Pervis switches off a little sometimes when tracking back, see West Ham.
Pervis probably shades it going forward, but overall, not loads in it...
