Middlesbrough striker Tuncay Sanli is backing old club Fenerbahce to shock Chelsea tonight in their Champions League quarterfinal.

"Wednesday will be a massive occasion. There will be a very, very big atmosphere in Fenerbahce and Chelsea will have to be ready," he said.

"Galatasaray have won big things in Europe before, but never Fenerbahce. It would be huge in Turkey if they could get past Chelsea.

"Chelsea are going to have to be careful, I know everyone expects Chelsea to just ease through but it's not going to be as easy as people think. Fenerbahce are a very good team with some very good players.

"Alex, Mateja Kezman, Stephen Appiah, although he is injured, Roberto Carlos, Deivid, I could name more.

"I'm sure Fenerbahce will win the first leg then it will be all about what happens in the return in London. I still have many friends at the club and if they ask me any questions about Chelsea I will tell them."
