Actually Samsunspor have a seemingly very good core of players in them.They've got Vlado Petkovic as the team's headcoach. He enjoyed fantastic success at Young Boys Bern, as he promoted top quality players to the world stage, including Seydou Doumbia and Thierry Doubai.
They have a decent goalkeeper in Ertugrul Taşkıran, on loan from Fenerbahce. He was a key player for Fenerbahce A2 (U21s) team when I worked there. Sometimes flops in crosses department, but still OK. Just 21 y-o.
Defence seems to be the weakest area. They have former PSV centre-back Andre Bahia, who seems to be the only decent players in that unit. Valdomiro, Hakan Arslan and Kemal do not seem sufficient.
They have Michael Fink, formerly of Beşiktaş and Monchengladbach in the midfield, partnered by Colombian Dominguez Cabezas, who they signed from FC Sion.
On the right side plays Simon Zenke, Nigerian powerhouse wingforward. On the left they usually put Pal Lazar of Hungary, or Ekigho Ehiosun of Nigeria. Ekigho is the guy who scored both goals vs Galatasaray last week, as they went up 2-0, before losing 2-4.
The striker since the beginning of the season has been Aristide Bance, former Mainz striker. And now that Gekas arrived for that position, I could see Bance either downgraded to the bench, or put on the left side instead of Ekigho.
As stated, Samsunspor do have a very good core of players, plus a decent coach. Will they turn things around in the second half of the season, I don't know but there's every reason to be hopeful.
