The Robertson of 3 years ago maybe but not now. Been poor for a couple of seasons, Pervis now far superior.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, and Robertson does cross a good ball.
Do I want Robertson in our team though? No. Pervis suits our style more.
