Agreed! Evans, Jones & Smalling just don't have the 'complete player' package that is required, for at least ONE of the CB's to possess. They all have their qualities, just can't seem to be consistent, reliable or indeed 'hungry' enough for the team.
Look at Vida & Rio; the reason they worked so well together is that they complimented each other. They were both strong characters, and as much as Vida was the more talented of the two, Rio had the lions share or passion, drive & determination that is so much lacking in the current squad. They ran the game from defence, they were relied on time after time, and barring some stupid errors (or Krypotonite players, such as Torres for Vida,) gave the team confidence in the back 4 who were also the driving force behind many of United's attacks. We need this again... Sooner rather than later. Before we 'do a Liverpool.' At least we have the financial investment in place to do it, and I do have faith in LVG that it will be spent wisely, unlike Moyes. Of course players prices will be inflated because we are not in the CL, but quite honestly this is knock-on effect from SAF relying too heavily on young players, putting too much faith in 'the kids.' It paid off with 'the class of 92,' but the world will never see a group of players like that again. Not only that, no PL club would be willing to try. Perhaps wisely. Before LVG, it had been too long since we signed some real & proven world-class quality.
EDIT - Oh, apart from RVP, who shown that proven quality is needed too - after-all, he did win us the tittle.
