I think some people need to cool their jets about Caceres, and yes I will confess to loving this bloke.
Still, he has proven he is capable in any defensive position he plays; he ably plays as either a RB or LB for Uruguay, he has served us well at RB/RWB (remains largely untested in a LB/LWB role here at Juve), and both at Sevilla and during our injury semi-crisis in the winter of 11/12, Caceres did very well to preserve our unbeaten run playing at CB, partnered by either Barzagli, Bonucci, and when both of those two were out, Vidal. He has the experience too, at 22 he was in great form for Uruguay when they went all the way to 4th place at the last world cup, only to trump that in the 2011 Copa America win (scoring the winning penalty with admirable composure and aplomb). Let's keep this in perspective, last year he was compromised by his knee injury in the pre-season at the Trofeo Berlusconi, then he suffered another niggle before that terrible car accident, then just when we was on the verge of coming back this year he suffered yet another set-back, after which the team (and obviously himself) opted for minor surgery. Now considering he's had little game time and is likely rusty, he did bloody well when thrown into the deep end at the Santiago Bernabeu in the previous game against Madrid, and his one critical error in this last game aside, played even better. Contrast that with the continuity that Chiellini and Bonucci have had over the last few years, and I'm certainly not putting Martin and Giorgio in the same category, Chiellini made a couple of silly slip-ups that are very uncharacteristic, but we can all agree that even the best of players suffer dips in form and lapses of judgement. However, look at the game time Bonucci gets and consider the number of blunders he has made, errors that from time to time determine the outcome of matches. There are players that have merited much more criticism than Martin, especially given his recent circumstances, we should be grateful to have such a champion that sits on our bench, ready and willing to face any opponent with fierce grinta, endless endeavour and unyielding determination, as he does.
