WhoScored - With less than a month to go before the season kicks off, carrying on from our focus on a number of top young full-backs across Europe, we look at a handful of centre-backs who will be looking to continue their impressive development in the 2012/13 campaign. The following five players have been chosen as a few lesser-known alternatives to keep an eye on next term, and all will begin the season under the age of 23.
Guess most of these CB will get to join a big club soon
Hummels should be on this list and he is only 23, could be the world's best in a few seasons
