Tasci is an option.
With Mats Hummels staying at Borussia Dortmund, the question becomes, "Are there any options that are equally as good as Mats Hummels in the transfer window?"
Let's look at the options.
The most affordable option is to not buy a CB and instead go with one of Barça's youth products. Marc Bartra and Marc Muniesa will be part of the first team next season. Both lack experience but what better way to get experience than with trial by fire, right?
Barcelona can acquire their former Masia product Alberto Botia for only €2.5 million due to a clause in his contract. Botia currently plays for Sporting Gijon.
Rumors have gone around that Barcelona is also interested in Chelsea's David Luiz as well. Another Premier League player who's name has come up is Arsenal's Thomas Vermaelen. Both Luiz and Vermaelen would certainly come with a heavy price tag, easliy nearing €30 million.
Olympique Lyon's Dejan Lovern is another player that Barcelona are apparently considering. The Croatian defender has an estimated transfer value of €14 million.
On Monday, German international and VfB Stuttgart center-back Sedar Tasci told Bild (Germany) he is being considered to go to FC Barcelona.
"I've heard that I'm a candidate for Barca. If an offer comes from Barcelona, you have to get together and have talks."
According to Bild (via CrunchSports.com), Tasci has a €10 million release clause in his contract and is signed until 2014.
It's a tough call to decide who would be the best option for Barcelona. Of course their youngsters need the playing time and would be the cheapest option as well. Alberto Botia at €2.5 million is not a bad deal.
If Tito wants to make a splash in the transfer window, he can go after David Luiz or Thomas Vermaelen but the price may be higher than €30 million. Both Lovern and Tasci are young and would come relatively inexpensively.
But would any of the players mentioned be as good or a better option than Mats Hummels would have been? Also, are there going to be other top center-backs hitting the transfer market anytime soon? These are some of the things Tito Vilanova and Sandro Rosell need to consider.
