Why?
Even though I was and still am one of the biggest (perhaps the biggest) critic of Caceres, I watched Lazio many many manyyyy times to know that Lichtsteiner is average, with the difference between the two being that there is a lot of room for improvement in Caceres' case, while in Licht's case, he's already in his best years.
The Swiss guy can indeed play a very good match from time to time, but apart from being inconsistent, very inconsistent, he also doesn't impress AT ALL in defense. Some could argue that Licht played his better matches as a MR than a RB.
So, even though I won't dare say that Martin is better than Lichtsteiner, I don't see why do you think that the Swiss is so much better (with what you said, I believe you're implying that Caceres is a much inferior player).
P.S: And I heard too that he was very good in France, but he's playing his second season in Lazio and on 1/4 of the matches he was good, on 1/4 very bad, while in the other half he was nothing more than average. He even lost his place in the starting XI at one point.
