Everything, what I have read so far indicates, he is a buy. Apparently, he pushes it hard to join Chelsea. So, he wants to play for the club which always helps the matter. Also, I like the fact he is a German. German league is not too soft & Chelsea needs tougher players. Enough of samba boys & their joggling techniques. Bulk up the team with toughness. Do you remember Ballack ? I thought he was great in his hay days.
