Former Germany goalkeeper Timo Hildebrand has revealed he is considering a move to Celtic.
Celtic are in the market for a goalkeeper following the sale of Artur Boruc to Fiorentina and had been keen to tie up a deal for England's David James, but that move appears to have stalled.
Hildebrand, 31, is also available on a free transfer after his deal at Hoffendeim expired and he told Bild: "Celtic are interested and that is very interesting for me."
Meanwhile, defender Jos Hooiveld has revealed his fury after Celtic's 3-0 defeat to Braga in the first leg of their Champions League qualifier.
Hooiveld, who joined from AIK in January, told the Daily Record: "If I'd still been playing for my old club in Sweden, I'm sure I would have broken something after the game. At this moment in my career at Celtic, I have just come back from an injury and people don't really know what kind of player I am.
"I'm not in a position within the group yet where I can go into the dressing room and grab people by the throat, but I felt like doing it. This is the first chance I have had to get into the Champions League and if we screw it up in this way it would be frustrating.
"It actually gets more frustrating when I talk about it. How did I view our performance? It was s**t. We lost 3-0 and that was bad enough but if you look at how the 3-0 scoreline came about you can see it was just too easy for Braga.
"That is what bugs and bothers me the most - how easily we gave goals away."
