It smooths relations, though. In my opinion, he's taking a really unnecessary "holier than thou" stance on hand-shaking. First Terry and now Suarez.
Like I say, it would've been really interesting to see how it would've panned out had Suarez shaken hands with Evra. Turdinand, I'm guessing, still wouldn't have offered his hand to Suarez, but I'm sure he wouldn't have got anywhere near the same backlash.
